Sample Code

This sample code is only representative of what could be done. It is provided only to give a general outline. You will need to use your initiative and industry best practices to find a solution that is suitable for the application.

// talawa/lib/widgets/oauth/oauth_button.dart
import 'package:flutter/material.dart';
class OAuthButton extends StatelessWidget {
  final String label; final Color color; final VoidCallback onPressed; final bool loading;
  const OAuthButton({super.key, required this.label, required this.color, required this.onPressed, this.loading=false});
  @override Widget build(BuildContext context) {
    return ElevatedButton(
      onPressed: loading?null:onPressed,
      style: ElevatedButton.styleFrom(backgroundColor: color),
      child: loading? const CircularProgressIndicator.adaptive() : Text(label),
    );
  }
}

// talawa/lib/config/oauth_config.dart
class OAuthConfig {
  static const googleClientId = String.fromEnvironment('GOOGLE_CLIENT_ID', defaultValue: '');
  static const googleRedirectUri = String.fromEnvironment('GOOGLE_REDIRECT_URI', defaultValue: 'talawa://oauth/callback');
  static const githubClientId = String.fromEnvironment('GITHUB_CLIENT_ID', defaultValue: '');
  static const githubRedirectUri = String.fromEnvironment('GITHUB_REDIRECT_URI', defaultValue: 'talawa://oauth/callback');
