Error Related To Flutter Provider Package

I am building a setting widget in my flutter app and I am getting this error : Error: Could not find the correct Provider above this SettingsForm Widget Update Adding whole debug s

Solution 1:

Because you have to declare the provider class above the class were your using it , if u find this ans crt mark it as crt

@overrideWidgetbuild(BuildContext context) {
returnMultiProvider(
  providers: [
    ChangeNotifierProvider(create: (ctx) =>MyUser(),),
    
  ],
  child: MaterialApp());

Solution 2:

You have to warp the parent class with the provider class you are using inside. For doing so the easiest way is to add a static method in widget havingMaterialPageRoute which helps to navigate to SettingsForm screen.

class SettingsForm extends StatefulWidget {

  static Widget getWidget() {
    return new Provider(
        create: (_) => MyUser(),
        child: ChangeNotifierProvider(
          create: (BuildContext context) => MyUser(),
          builder: (_,_) => SettingsForm()
        ),
     );
  }

  @override
  _SettingsFormState createState() => _SettingsFormState();
}

To open SettingsForm screen just call getRoute function on button pressed. Check the below code.

Open SettingsForm screen from Home screen

 void _showSettingsPanel() {
      showModalBottomSheet(context: context, builder: (context) {
        return Container(
          padding: EdgeInsets.symmetric(vertical: 20.0, horizontal: 60.0),
          child: SettingsForm.getWidget(), <-- Here
        );
      });
    }
