I have two FlatButtons in a row. The row is a column which is in turn in a container that is used for the padding of the screen. This container has padding of right:20 and left:20. I want my buttons to be 20 in from left and 20 in from the right to keep everything aligned in my column. I know the FlatButton widget has default padding and I've tried the solutions in this question Changing the buttons to GestureDectectors widgets works with alignment but doesn't have a very nice user experience, the area to click is too small maybe. Ideally I'd like to remove the padding of the FlatButton on one side left/right depending on which button. Here is my code
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
FlatButton(
child: new Text('SIGN IN',
style: Theme.of(context).textTheme.body1),
onPressed: () {
Navigator.push(
context, SignInPage(widget.onSignedIn));
},
),
new FlatButton(
child: new Text(
'SIGN UP',
style: Theme.of(context).textTheme.body1,
),
onPressed: () {
Navigator.push(
context, SignUpPage(widget.onSignedIn));
},
),
]),
Now with the deprecation of the FlatButton for TextButton
TextButton(
style: TextButton.styleFrom(padding: EdgeInsets.all(0)),
...
)
Use zero padding, for example
padding: EdgeInsets.zero,
To remove extra space from around TextButton and OutlineButton which replace FlatButton use this:
style: OutlinedButton.styleFrom(
tapTargetSize: MaterialTapTargetSize.shrinkWrap,
)
try to use option 'padding: EdgeInsets.only( depends which side u wanna padding )'
FlatButton(
padding: EdgeInsets.only(left: 10.0, right:10.0),
child: new Text('SIGN IN',
style: Theme.of(context).textTheme.body1),
onPressed: () {
Navigator.push(
context, SignInPage(widget.onSignedIn));
},
),
SizedBox(
height: 25,
child: ElevatedButton(
onPressed: onPressed,
style: ElevatedButton.styleFrom(
padding: EdgeInsets.zero,
shape: RoundedRectangleBorder(
borderRadius:
BorderRadius.circular(kDefaultPadding))),
child: const Text("More"),
)
)
The FlatButton is now deprecated and you can use TextButton.
Even if you set padding to 0, there is still some padding left. To remove it completely you can use RawMaterialButton as suggested by #Arshak here.
Example:
RawMaterialButton(
constraints: BoxConstraints(),
padding: EdgeInsets.all(5.0), // optional, in order to add additional space around text if needed
child: Text('Button Text')
)
I know answer is right there but It took me hours to do this. So I thought to add it as answer also.
NOTE: Im using Navigator.of(context).push to push ModalRoute,

please help me
thanks solve my problem with this padding on bottom of textfield
Padding(
padding: EdgeInsets.only(
bottom: MediaQuery.of(context).viewInsets.bottom));
and mare reverse list
This worked for me...
First add this
final bottom = MediaQuery.of(context).viewInsets.bottom;
Then use a SingleChildScrollView() to wrap around the main widget (whatever you're using, e.g. Column, ListView, etc) like this...
You need "reverse: true"
Widget build{
return Scaffold(
body: SingleChildScrollView(
reverse: true;
child: Container(...
You also need these two lines of code for the Scaffold as well..
return Scaffold(
resizeToAvoidBottomInset: false,
resizeToAvoidBottomPadding: false,
body: SingleChildScrollView(...
and finally, reference the 'bottom' for your EdgeInsets..
body: SingleChildScrollView(
reverse: true,
child: Padding(
padding: EdgeInsets.only(bottom: bottom),
child: Container(...
You need to wrap everything in a SingleChildScrollView and set the reverse to true.
SingleChildScrollView(
reverse: true,
child: Container(),
);
Just that worked for me!
I had a similar problem. I try all solution, but didn't work.
Finally I removed
<item name="android:windowFullscreen">true</item>
from my styles.xml file in android folder, and fix the problem.
There are few methods for this (as of Dec 3rd 2018):
You can read this for a better solution: When i select a Textfield the keyboard moves over it.
Inside Scaffold() add: resizeToAvoidBottomPadding: false,.
You can also wrap your TextWidget with SingleChildScrollView(). This will allow you to scroll whenever the keyboard is shown.
Set resizeToAvoidBottomInset to false inside your Scaffold Widget.
Note that resizeToAvoidBottomPadding will be deprecated.
Scaffold( resizeToAvoidBottomInset: false, ...)
I use form elements in modal_bottom_sheet plugin. I solved it by just adding the following code to SingleChildScrollView.
padding: EdgeInsets.only(bottom: MediaQuery.of(context).viewInsets.bottom)
Too add to the commonly accepted answers here which is
body: SingleChildScrollView(
reverse: true,
child: Container(
child: Padding(
padding: EdgeInsets.only(bottom: bottom),
child: Stack(
fit: StackFit.loose,
children: <Widget>[
I added a thing to the bottom inset to prevent it from going too high.
var bottom = MediaQuery.of(context).viewInsets.bottom;
bottom = max(min(bottom, 80), 0);
What worked for me was combining the docs with tips over here. It uses, LayoutBuilder, SingleChildScrollView, Padding (with bottom hack) and finally, ConstrainedBox (to use Expanded). By combining these It works with Expanded widgets inside Columns.
The docs (from where LayoutBuilder comes):
https://api.flutter.dev/flutter/widgets/SingleChildScrollView-class.html
Structure
return Scaffold(
resizeToAvoidBottomInset: false,
resizeToAvoidBottomPadding: false,`
body: SafeArea(
child: Container(
child: LayoutBuilder(builder:
(BuildContext context, BoxConstraints viewportConstraints) {
return SingleChildScrollView(
reverse: true,
child: Padding(
padding: EdgeInsets.only(bottom: bottom),
child: ConstrainedBox(
constraints: BoxConstraints(
minHeight: viewportConstraints.maxHeight,
maxHeight: viewportConstraints.maxHeight),
child: Column(
SingleChildScrollView does solve the problem while the resizeToAvoidBottomInset is set to true, while setting it to false would be a not recommended solution. Let me explain why:
When user presses the TextField, usually a virtual keyboard will popup and takes up a large portion of the bottom space on the screen. In such case, problem would occur, if the TextField is near said bottom, it will be covered by the keyboard (resizeToAvoid... set to false), and user will be unable to see what they've typed in; if there are other widgets below the TextField (when resizeToAvoid is true, e.g. buttons in the same Column with TextField), there will be overflow because there is no space for them to show on the remaining viewport.
Speaking from a user's perspective, what we want is:
TextField who gets focus is always visible.
No bottom overflow and bugged graphics.
However, such description is not technical, it does not tell us how exactly do we implement it. What we actually want is, make the whole layout scrollable, and allow Scaffold to resize. When the viewport resizes, anything below the focused TextField scrolls away to the invisible bottom, and the TextField itself snaps to the keyboard.That's why SingleChildScrollView + resize = true is what we want.
To have a centered content first on build method I added this:
final bottom = MediaQuery.of(context).viewInsets.bottom;
and return this:
return GestureDetector(
onTap: () => FocusManager.instance.primaryFocus?.unfocus(),
child: Scaffold(
resizeToAvoidBottomInset: false,
body: Stack(
fit: StackFit.expand,
children: [
///Content
Align(
alignment: Alignment.center,
child: SingleChildScrollView(
reverse: true,
child: Padding(
padding: EdgeInsets.only(bottom: bottom),
child: Column(
children: [
MyContent()
],
),
),
),
),
///Button
Align(
alignment: Alignment.bottomCenter,
child: MyBottomButton()
)
],
),
),
);
And it works very well with keyboard flow
In my case, there was were important to use only small padding, otherwise when open the keyboard it makes a big mess.
Padding(padding: EdgeInsets.only(bottom: 20)
Check my solution:
child: Scaffold(
resizeToAvoidBottomInset: false,
resizeToAvoidBottomPadding: false,
body: Container(
color: Colors.black,
child: SingleChildScrollView(
reverse: true,
child: Padding(
padding: EdgeInsets.only(bottom: 20),
child: Container(
child: ReservationCard(
),
),
),
),
)
For Android, check for windowSoftInputMode. (AndroidManifest.xml)
android:windowSoftInputMode="adjustResize"
I have used the Expansion Tile to generate a Expansion List View.
I'm facing some customization issues in Expansion Tile Header.
Below is my code.
ExpansionTile(
title: Container(
child: Text(
getCategory(i),
style: TextStyle(
color: Colors.white,
),
),
color: Colors.black
),
children: <Widget>[
new Container(
height: 60.0,
margin: const EdgeInsets.only(top:10.0, left: 10.0, right:10.0, bottom: 10.0),
decoration: BoxDecoration(
color: Colors.blue,
borderRadius: new BorderRadius.all( Radius.circular(5.0) ),
),
),
new Container(
height: 60.0,
margin: const EdgeInsets.only(top:10.0, left: 10.0, right:10.0, bottom: 0.0),
decoration: BoxDecoration(
color: Colors.green,
borderRadius: new BorderRadius.all( Radius.circular(5.0) ),
),
)
],
backgroundColor: Colors.white,
)
I'm getting below result.
What I'm expecting to have is below.
If anyone know a workaround to customize the header color, please advice.
If you check the source code of the ExpansionTitle , you will notice that the header item is a ListTile , so you can't change the background because it hasn't a parent with a color property.
I modified a little the class to support what you need.
Add this file to your project: https://gist.github.com/diegoveloper/02424eebd4d6e06ae649b31e4ebcf53c
And import like this way to avoid conflicts because the same name.
import 'package:nameofyourapp/custom_expansion_tile.dart' as custom;
I put an alias 'custom' but you can change for any alias.
Usage:
custom.ExpansionTile(
headerBackgroundColor: Colors.black,
iconColor: Colors.white,
title: Container(
...
Remember, Flutter has a lot of Widgets out of the box, but If any of them don't fit what you need, you'll have to check the source code and create your own widget.
In my opinion, the more preferable way is wrap It with a new Theme, so It could work as expected:
Theme(
data: Theme.of(context).copyWith(accentColor: ColorPalette.fontColor, unselectedWidgetColor: ColorPalette.fontColor..withOpacity(0.8)),
child: ListView(
children: <Widget>[
ExpansionTile(
title: Text("Padding"),
children: <Widget>[
Text("Left"),
Text("Top"),
Text("Right"),
Text("Bottom"),
],
)
],
),
)
Instead of copy a full class to customize, check the source code, you could find more Theme attribute to override.
_borderColorTween
..end = theme.dividerColor;
_headerColorTween
..begin = theme.textTheme.subhead.color
..end = theme.accentColor;
_iconColorTween
..begin = theme.unselectedWidgetColor
..end = theme.accentColor;
_backgroundColorTween
..end = widget.backgroundColor;
If you want a more animatable widget or something, I would recommend diegoveloper's answer. Otherwise, just wrap It with Theme, so you won't need to maintain the Component, and get native flutter component.
A much easier way than all of those suggested is to wrap your ExpansionTile in a ListTileTheme.
Once you do this, you can change the backgroundColor to whatever you'd like. In my case, I've done the same thing with the ListTiles inside of the ExpansionTile so that the header can have one color and the children can have another color.
return ListTileTheme(
tileColor: Colors.grey.shade300,
child: ExpansionTile(
leading: Padding(
padding: const EdgeInsets.only(top:4.0),
child: Text('Outer Tile'),
),
title: null,
children: [
Slidable(
actionPane: SlidableDrawerActionPane(),
child: ListTileTheme(
tileColor: Colors.white,
child: ListTile(
title: Text('Inner Tile'),
subtitle: Text('subtitle'),
leading: FlutterLogo(),
),
),
)
],
),
);
I think this is easier than digging through the docs to find which Theme elements correspond to individual ListTile parameters.
I think better this solution more than custom list tile .
Widget customTheme(Widget child, BuildContext context) => Theme(
data: Theme.of(context).copyWith(
dividerColor: Colors.transparent,
dividerTheme: DividerThemeData(
color: Theme.of(context).colorScheme.background)),
child: child,
);
Code Gist
It seems the ExpansionTile was changed and you can now directly configure lots of colors. As an example, for the arrows:
return ExpansionTile(
// sets the color of the arrow when collapsed
collapsedIconColor: Colors.red,
// sets the color of the arrow when expanded
iconColor: Colors.green,
);
For changing trailing arrow icon color you can wrap expansion tile with Theme and make theme light and set accet color and primary color to dark and it will work.
return Theme(
data: ThemeData.light()
.copyWith(accentColor: darkAccent, primaryColor: darkAccent),
child: ExpansionTile(
title: Text(
data['number'],
style:
TextStyle(color: darkAccent, fontWeight: FontWeight.bold),
),
Another option which should work is wrapping both the entire expansion tile and each individual container in a Card() widget as they have a color property. The downside is that the background for your expansion will be colored as well as the title, but if you set a color for the child cards, they will not be affected by the parent an so they could be individually colored as you like.
For trouble with the arrow color: notice it's an ExpandIcon, defined as a local Widget expandIconContainer in _ExpansionPanelListState.build().
When your ExpansionPanel uses canTapOnHeader: true, you get ExpandIcon(onPressed: null), so the color used for the underlying IconButton is determined by Theme#disabledColor.
I use this great little plugin, much more flexible than the Flutter Material. You can change the background and borders and have custom icons for open and close states. https://pub.dev/packages/configurable_expansion_tile
I'm trying to implement my own TabBar design in flutter. I was able to get a pretty good result. However, when I tap another tab to change the tab, there is a highlight create by default as shown in the image here. I'm wondering if there is any way I can get rid of the square highlight on tapped. I've been looking around for like almost a day not and did not find any solution.
If anyone have any solution please let me know. Thanks.
Edited: as CopsOnRoad suggestion I wrapped the TabBar in the Container and set the color to Colors.transparent, but it does not really disappear so I tried to set the color to Theme.of(context).canvasColor for now.
Container(
color: Theme.of(context).canvasColor,
child: TabBar(
isScrollable: true,
indicator: ShapeDecoration(
color: Color(0xFFE6E6E6),
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(99.0)
)
),
tabs: List<Widget>.generate(
categories.length,
(index) => Tab(
child: Text(
categories[index],
style: TextStyle(
fontFamily: 'Hiragino Sans',
fontWeight: FontWeight.bold,
fontSize: 18.0,
color: Color(0xFF4D4D4D),
),
),
)
),
)
)
You can also disable the ripple/highlight/splash effect with the code below. Add the Theme with the data of ThemeData where the hightlight and splash color is both transparent.
return Scaffold(
appBar: PreferredSize(
preferredSize: Size.fromHeight(70),
child: Theme(
data: ThemeData(
highlightColor: Colors.transparent,
splashColor: Colors.transparent,
),
child: AppBar( ... )
That's the ripple effect. You can remove it by wrapping it in a Container and giving transparent color to it.
you should set tabbar splashFactory: NoSplash.splashFactory as this post mentioned.
TabBar(splashFactory: NoSplash.splashFactory,)
How to disable default Widget splash effect in Flutter?
Here is my custom solution from #Tempelriter
Theme(
data: Theme.of(context).copyWith(
highlightColor: Colors.transparent,
splashColor: Colors.transparent,
),
child: Container(
decoration: BoxDecoration(
color: Colors.gray,
border: Border.all(
color: Colors.red
),
borderRadius: BorderRadius.circular(50),
),
child: TabBar(
isScrollable: true,
tabs: [
Tab(text: 'comingSoon'),
Tab(text: 'selling'),
],
),
),
);
I had the similar issue. I tried to read the documentation and found it.
///
/// If non-null, it is resolved against one of [MaterialState.focused],
/// [MaterialState.hovered], and [MaterialState.pressed].
///
/// [MaterialState.pressed] triggers a ripple (an ink splash), per
/// the current Material Design spec.
///
/// If the overlay color is null or resolves to null, then the default values
/// for [InkResponse.focusColor], [InkResponse.hoverColor], [InkResponse.splashColor],
/// and [InkResponse.highlightColor] will be used instead.
final MaterialStateProperty<Color?>? overlayColor;
Finally just added overlayColor to transparent. It solved my issue.
overlayColor: MaterialStateProperty.all(Colors.transparent)
I'm new to Flutter and was trying to change the child icon color of FloatingActionButton. Child icon color is white by default.
How can i change that??
Given below is the code that i have worked on.
floatingActionButton: new FloatingActionButton(
onPressed: _incrementCounter,
tooltip: 'Increment',
child: new Icon(Icons.add),
backgroundColor: Colors.yellow,
), // This trailing comma makes auto-formatting nicer for build methods.
);
Thank you.
You can wrap in an IconTheme
child: new IconTheme(
data: new IconThemeData(
color: Colors.yellow),
child: new Icon(Icons.add),
),
or a Theme where iconTheme is set the way you want it
(not tested)
To change the color of child Icon, You have to set the color in the Icon() widget.
Here I am sharing the code snippet where I have set the red color.
floatingActionButton: FloatingActionButton(
tooltip: 'Increment',
child: new Icon(Icons.add, color: Colors.red,),
backgroundColor: Colors.yellow,
),
Flutter v17.4
This worked for me, if you just want to change to colour of icon.
floatingActionButton: FloatingActionButton(
child: Icon(Icons.add,
color: Colors.black, //The color which you want set.
),
onPressed: () => {},
),
MaterialApp theme: ThemeData
If using ThemeData in your MaterialApp to color your app like:
return MaterialApp(
title: 'Flutter Demo',
theme: lightThemeData, // this guy
darkTheme: darkThemeData, // and perhaps this guy
home: MyHomePage()
);
... you have 2 ways to color your FloatingActionButton (FAB) Icon color in ThemeData:
floatingActionButtonTheme: const FloatingActionButtonThemeData(foregroundColor: myColor)
onSecondary: myColor (used only if ↑↑↑ is missing)
final lightThemeData = ThemeData.from(
colorScheme: ColorScheme.fromSeed(
seedColor: Colors.blue,
brightness: Brightness.light,
primary: blue,
secondary: blue,
onSecondary: white, // FAB Icon color if FABTheme not provided like below
),
).copyWith(
floatingActionButtonTheme: const FloatingActionButtonThemeData(foregroundColor: Colors.green), // this guy works
iconTheme: const IconThemeData(color: white), // DOES NOT affect FAB Icon
accentIconTheme: const IconThemeData(color: purpleRain), // argumentFormerlyKnownAsFabIconColor - deprecated, DON'T USE THIS
);
In the above themeData example, the FAB Icon would be colored green.
Because onSecondary is used to color the FAB icon only if floatingActionButtonTheme is missing.
If neither of the above theme colors are provided, the FAB Icon will fallback to black color.
iconTheme and accentIconTheme both have no effect on FAB icon color.
FAB accentIconTheme change happened in Flutter 1.17.
