Change color of DataTable rows and columns - dart

Question

I have a small data table and i want to change the column and row background color.
But unfortunately there is no property in DataColumn or DataRow to achieve this.
The only way i found is through modifying the label of DataColumn
DataColumn(label: Container(child: Text('Person'),color: Colors.amberAccent,)),
but there is a default padding for the DataColumn and the color only applies to the text.
and here is my code:
class _ContactLocationsState extends State<ContactLocations> {
#override
Widget build(BuildContext context) {
return Center(
child: DataTable(columns: <DataColumn>[
DataColumn(label: Text('Person')),
DataColumn(label: Text('Rating')),
DataColumn(label: Text('Distance')),
DataColumn(label: Text('Max Price')),
DataColumn(label: Text('Fee')),
], rows: <DataRow>[
DataRow(
cells: <DataCell>[
DataCell(Text("test")),
DataCell(Text("test")),
DataCell(Text("test")),
DataCell(Text("test")),
DataCell(Text("test")),
],
),
]),
);
}
}

Answer 1

If you are still looking for answer, you can use MaterialStateColor property. Here is the working code
return DataRow.byIndex(
index: row.key,
color: MaterialStateColor.resolveWith(
(states) {
if (row.key % 2 == 0) {
return Colors.blue[50];
} else {
return Colors.white;
}
},
),

I found a way using that you can achieve exactly same look as table and also change the colors of background using Row and Expanded Widgets.
I hope that Following Code Help You.
import 'package:flutter/material.dart';
void main() => runApp(new MyApp());
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return new MaterialApp(
title: 'Flutter Demo',
theme: new ThemeData(
primarySwatch: Colors.blue,
),
debugShowCheckedModeBanner: false,
home: new MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> with SingleTickerProviderStateMixin {
AnimationController _controller;
#override
void initState() {
_controller = AnimationController(vsync: this);
super.initState();
}
#override
void dispose() {
_controller.dispose();
super.dispose();
}
#override
Widget build(BuildContext context) {
return Scaffold(
body: Container(
child: Center(
child: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Row(
children: <Widget>[
Expanded(
child: Container(
color: Colors.green,
child: Text("person")
),
),Expanded(
child: Container(
color: Colors.red,
child: Text("Rating")
),
),Expanded(
child: Container(
color: Colors.green,
child: Text("Distance")
),
),Expanded(
child: Container(
color: Colors.red,
child: Text("Max Price")
),
),Expanded(
child: Container(
color: Colors.green,
child: Text("Free")
),
),
],
),
Row(
children: <Widget>[
Expanded(
child: Container(
color: Colors.red,
child: Text("Test")
),
),Expanded(
child: Container(
color: Colors.green,
child: Text("Test")
),
),Expanded(
child: Container(
color: Colors.red,
child: Text("Test")
),
),Expanded(
child: Container(
color: Colors.green,
child: Text("Test")
),
),Expanded(
child: Container(
color: Colors.red,
child: Text("Test")
),
),
],
),

);
}
}
