Unhandled Exception: MissingPluginException(No implementation found for method check on channel plugins.flutter.io/connectivity)

Question

I already added connectivity plugin on my pubspec.yaml.

connectivity: ^0.4.6

But still getting this error:

E/flutter ( 4789): [ERROR:flutter/lib/ui/ui_dart_state.cc(148)] Unhandled Exception: MissingPluginException(No implementation found for method check on channel plugins.flutter.io/connectivity)
E/flutter ( 4789): #0 MethodChannel.invokeMethod (package:flutter/src/services/platform_channel.dart:314:7)
E/flutter ( 4789):
E/flutter ( 4789): #1 Connectivity.checkConnectivity (package:connectivity/connectivity.dart:73:47)

error connectivity is from this line :

  Future<ConnectivityResult> checkConnectivity() async {
    final String result = await methodChannel.invokeMethod<String>('check');
    return _parseConnectivityResult(result);
  }

and I never modified this package, But still get this error no matter what version of this plugin that I use. I hope anyone can help me to solve this error, thank you. Sorry for my bad English.

Answer 1

This error mostly occurs when you try to Hot Reload or Hot Restart after just adding new package to your pubspec.yaml.

Just stop the running project(app) and then freshly run it again. So that the added package(which contains the implementations) also pushed to the device

Answer 2

Flutter clean on terminal, stop the build and running again worked for me
