I have created a flutter app on which I am want to set up 3 flavors. Each one of them is having different font, different set of images and different set of string file. How can I use particular font, images and String file for that particular flavor? Thanks in advance!

dart flutter

you can create app config file.

import 'package:flutter/material.dart';

enum Flavor { FLAV1, FLAV2 }

class AppConfig extends InheritedWidget {
  final String appTitle;
  final String buildFlavor;
  final Flavor flavor;
  final Widget child;
  final ThemeData themeData;
  final String s3BucketURL;
  final String stripeKey;

  AppConfig(
      {@required this.appTitle,
      @required this.buildFlavor,
      @required this.themeData,
      @required this.flavor,
      @required this.s3BucketURL,
      @required this.stripeKey,
      @required this.child});

  @override
  bool updateShouldNotify(covariant InheritedWidget oldWidget) => false;

  static AppConfig of(BuildContext context) {
    return context.dependOnInheritedWidgetOfExactType();
  }
}

create folders assets/ assets/1/ assets/2/

add to pubspec.yaml

and you can use the indexs of flavors to get assets when accessing those.

SvgPicture.asset(
                    'assets/${AppConfig.of(context).flavor.inex}/splash_logo.svg',
                    colorBlendMode: BlendMode.srcIn,
                    color: Theme.of(context).primaryColor,
                  )

You can add different app config files when init. create different main files like main_flav1.dart, main_flav2.dev.

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  var configureApp = AppConfig(
    appTitle: 'App staging',
    buildFlavor: 'Staging',
    flavor: Flavor.FLAV1,
    themeData: PreOrderTheme.flav1Theme,
    stripeKey: 'pk_s',
    s3BucketURL: 'https://sssss.net',
    child: PreOrderApp(repository: Repository(baseURL:"https://webapi.net/api")),
  );
  return runApp(configureApp);
}
