Type 'GeolocationOriginal' is not assignable to type 'Provider'. Type
'GeolocationOriginal' is missing the following properties from type
'FactoryProvider': provide, useFactory
Change the import code.

to

In the module that this component is imported in, try adding the CommonModule

This might be one of the issues.
I have a podo class CarStorage for angular to inject.
class CarStorage {
int _carIdCounter = 0;
...
I wire it in using type:
module
..type(CarForm)
..type(CarItemsList)
..type(CarStorage)
;
It works in dartium but fails to load in dart2js. I get the following error:
Illegal argument(s): No type factory provided for CarStorage! (resolving GarageAppController -> CarStorage)
I discovered through some bug reports and guess work you need to add the DI Injectable annotation:
import "package:angular/angular.dart";
#Injectable()
class CarStorage {
...
edit: Fixed the import.
Do NOT use import 'package:di/annotations.dart'; this causes errors
I'm trying to learn how to implement logging using the examples/tutorial in:
http://blog.dartwatch.com/2013/05/campaign-to-use-real-logging-instead-of.html#comment-form
But having imported the libraries this line in main will not compile because the class 'PrintHandler' is not recognized and Google has not been a help in this case. My server application consists of a main and three classes. I'm new at Dart. Below I've extracted the logging code that I added.
In what library is 'PrintHandler'? Is this a class I need to write?
library server;
import 'package:logging_handlers/logging_handlers_shared.dart';
import 'package:logging/logging.dart';
final _serverLogger = new Logger("server"); // top level logger
void main() {
Logger.root.onRecord.listen(new PrintHandler()); // default PrintHandler
_serverLogger.fine("Server created");
}
class A {
}
class B {
}
class C {
}
It looks like the class was changed to LogPrintHandler but the tutorial and documentation were not updated.
I am creating a scientific calc app in DART . i dont knw how to use trignometric functions like sine , cosine . i used "math.sin()" , but it throws an exception "NO top-level getter math.get declared " how to solve it ? thanks in advance
To use trigonometric functions in Dart, import the dart:math library. For example:
import 'dart:math';
main() {
print(sin(pi));
}
If you want, you can import with a prefix to avoid namespace collisions:
import 'dart:math' as Math;
main() {
print(Math.sin(Math.pi));
}
In my Grails app, I need to bind a request parameter to a Date field of a command object. In order to perform the String-to-Date conversion, one needs to register an appropriate PropertyEditor in grails-app\conf\spring\resources.groovy
I've added the following bean definiton:
import org.springframework.beans.propertyeditors.CustomDateEditor
import java.text.SimpleDateFormat
beans = {
paramDateEditor(CustomDateEditor, new SimpleDateFormat("dd/MM/yy"), true) {}
}
But I'm still getting an error:
java.lang.IllegalArgumentException: Could not parse date: Unparseable date: "04/01/99"]
I think there's probably just something wrong with the way I've defined the bean, but I've no idea what?
The piece you are missing is registering of the new property editor. The following worked for me when I upgraded to Grails 1.1 and had to bind dates in the MM/dd/yyyy format.
grails-app/config/spring/resources.groovy:
beans = {
customPropertyEditorRegistrar(util.CustomPropertyEditorRegistrar)
}
src/groovy/util/CustomPropertyEditorRegistrar.groovy:
package util
import java.util.Date
import java.text.SimpleDateFormat
import org.springframework.beans.propertyeditors.CustomDateEditor
import org.springframework.beans.PropertyEditorRegistrar
import org.springframework.beans.PropertyEditorRegistry
public class CustomPropertyEditorRegistrar implements PropertyEditorRegistrar {
public void registerCustomEditors(PropertyEditorRegistry registry) {
registry.registerCustomEditor(Date.class, new CustomDateEditor(new SimpleDateFormat("dd/MM/yy"), true));
}
}
