mock_package_info.dart

import 'package:flutter/services.dart'; 
import 'package:flutter_test/flutter_test.dart';

void mockPackageInfo() {
  const channel = MethodChannel('plugins.flutter.io/package_info');

  handler(MethodCall methodCall) async {
    if (methodCall.method == 'getAll') {
      return <String, dynamic>{
        'appName': 'myapp',
        'packageName': 'com.mycompany.myapp',
        'version': '0.0.1',
        'buildNumber': '1'
      };
    }
    return null;
  }

  TestWidgetsFlutterBinding.ensureInitialized();

  TestDefaultBinaryMessengerBinding.instance.defaultBinaryMessenger
      .setMockMethodCallHandler(channel, handler);
}
