MissingPluginException(No implementation found for method close on channel flutter_webview_plugin) about flutter_webview_plugin HOT 14 CLOSED

It's like you did get the updated dart code but not the iOS/Android one.
Can you try to remove pubspec.lock and .pub then redo a flutter packages get ?

from flutter_webview_plugin.

I just fixed the issue on my side right now. I stop first the app then;

flutter clean
flutter clean cached --all
then ctrl + s in pubspec.yaml

in my pubspec i have this, 'flutter_webview_plugin:' and my flutter version is 1.17.5

from flutter_webview_plugin.

Did you solve in some way? I'm having the same error

from flutter_webview_plugin.

I was having the same problem but it went away on its own, probably something wasn't clean. Restarted my Mac on Monday morning, rebuild and reloaded everything and my Help route via WebView is working fine on both platforms.

from flutter_webview_plugin.

flutter clean might help. I have this occasionally recently that some changes don't take effect.

from flutter_webview_plugin.

Yes, that's what I meant by "rebuilt and reloaded everything", flutter clean run forces it to rebuild everything in sight. Is now my go-to first thing to try when changes don't appear in a "hot reload"

@lejard-h and others devs...
I have already performed the procedures of [Restart mac, flutter clean] and still it continues with error below for iOS..... and for Android the project can not be built

ERROR:

If you use the AS, please check the file - > project structure - > modules - > dependences, maybe could solve the problem

Hey I am having the same problem. Did you find a solution ?

Hey I am having the same problem. Did you find a solution ?

i have same issue,did you fix ?

from flutter_webview_plugin.

No i did not fix the issue !

from flutter_webview_plugin.

No i did not fix the issue !

it work fine in single flutter project but not in a exiting project add into flutter
what about you?

if cant fix ,what should we do? give up flutter in this function,use native develop it?

from flutter_webview_plugin.

No i did not fix the issue !

hey my friend ,i am so exited to share you my way to fix it, yes, i fixed it, maybe it is a bug

1. it's happend in a exiting project add into flutter
2. i add into flutter by offical wiki but i didnt use flutterview or flutterfragment

i create a activity class ShopActivity : FlutterFragmentActivity()
then
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
GeneratedPluginRegistrant.registerWith(this)
....}
when i use flutter-webview-plugin logcat print "MissingPluginException(No implementation found for method close on channel flutter_webview_plugin) "

i think flutter-webview-plugin maybe not register successfully
so i add " FlutterWebviewPlugin.registerWith(this.registrarFor("com.flutter_webview_plugin.FlutterWebviewPlugin"))"

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)

    GeneratedPluginRegistrant.registerWith(this)
    FlutterWebviewPlugin.registerWith(this.registrarFor("com.flutter_webview_plugin.FlutterWebviewPlugin"))

}

then success, that maybe a flutter bug in a exiting project add into flutter
我只是用取巧的方式绕过了这个问题,希望官方可以重视修复
