sharedpreferences - Flutter: Unhandled exception: MissingPluginException(No implementation found for method getAll on channel plugins.flutter.io/shared_preferences)

Question

My Flutter application uses the Flutter SharedPreferences plugin and send values to the iOS side with platform.invokeMethod. If I start the application, I have this error:

[VERBOSE-2:dart_error.cc(16)] Unhandled exception:
MissingPluginException(No implementation found for method getAll on channel plugins.flutter.io/shared_preferences)
#0      MethodChannel.invokeMethod (package:flutter/src/services/platform_channel.dart:278:7)
<asynchronous suspension>
#1      SharedPreferences.getInstance (package:shared_preferences/shared_preferences.dart:25:27)
<asynchronous suspension>
#2      main (file:///Users/Developer/workspace/flutter-app/q_flutter2/lib/main.dart:25:53)

#4      _RawReceivePortImpl._handleMessage (dart:isolate/runtime/libisolate_patch.dart:165:12)

If I comment the function to send the value to iOS side, the error is not displayed and the SharedPreferences is working.

Someone can help me?

Answer 1

No implementation found for method getAll on channel plugins.flutter.io.

The above will occur when you setup the plugin for the first time, so it has to be reinstalled.

Therefore, uninstall and reinstall your application.
