How to fix "MissingPluginException (No implementation found for method)" in Flutter

When developing Flutter apps, you may see the “MissingPluginException (No implementation found for method)” error. This means Flutter can’t find the native code for a plugin method.

Why does the “MissingPluginException” error occur?

This error means that Flutter can’t find the native implementation for a plugin method you’re trying to use. It usually happens when:

  • A plugin isn’t registered correctly.
  • You’ve added a new plugin but haven’t rebuilt the app.
  • The plugin doesn’t support your current platform (e.g., web, desktop, or a specific OS).
  • You’re running on an emulator or simulator that needs a full restart.

How to fix the “MissingPluginException” error

Here are the steps to resolve this error:

1. Clean and fetch dependencies

First, run the following commands in your project directory:

flutter clean
flutter pub get

This removes old build files and fetches your dependencies again, ensuring everything is up to date.

2. Restart your app (not just hot reload)

A simple hot reload won’t register new plugins. Make sure to fully restart your app:

  • Stop the running app.
  • Rebuild and run it again using flutter run or your IDE’s restart option.

3. Check platform support

Not all plugins support every platform. Double-check the plugin’s documentation to ensure it works on your target OS (Android, iOS, web, desktop, etc.).

4. Additional troubleshooting

  • If you’re using an emulator or simulator, try restarting it.
  • Make sure your Flutter and Dart SDKs are up to date: 
    flutter upgrade
  • If the problem persists, try removing and re-adding the plugin in your pubspec.yaml.

Conclusion

The “MissingPluginException” error in Flutter is common but easy to fix with the right steps. By cleaning your project, fetching dependencies, and fully restarting your app, you can resolve most plugin registration issues. Always check platform compatibility and keep your tools up to date for a smooth development experience.
