Flutter share_plus is not working and getting error [duplicate] - flutter

Question

I am trying to use the plugin
_launchURL(url) async {
await launch("www.google.com");
}
I have put "www.google.com" just for debugging purposes.
The error I get is MissingPluginException :

restarting the app from ide doesn't work.

Answer 1

If you are using hot restart or hot reload, it won't do the trick.
Since Flutter has to inject plugin dependencies into the platform-specific parts of your app, hot restart/hot reload is not enough to trigger the injection.
Check this issue for more.
Close the app and execute flutter run command.

Answer 2

flutter clean
Inside the console did the job as stated here

Answer 3

I faced this Error when using Url_launcher package. just had to stop and run the app, issue got solved

Answer 4

Simply Run these commands..
either--
Flutter clean
or
Invalidate Caches/Restart

Answer 5

Had problem while using flutter toast dependency and dependencies like facebook_login. I followed these steps and resolved it:
First, u need to test whether these toast and shared preference dependencies are causing problems or some other dependencies cause the problem.
For testing that, u need to create a new seprate flutter project having the same flutter toast and shared preference dependency and check now if u r able to get toasts or not.
If u r getting toast so there is no problem with ur toast dependency.
The problem might be in ur one of the social media dependency.
In my case, I followed the above steps and found that problem was in facebook dependency. Finally, I found that I did not provide details of my app at facebook developer console. So implemented that and my app was fine.

Answer 6

In my case it was for the cached_network_image plugin , I have removed cached_network_image from pubspec.yaml and replaced the implementation with Image.network and the problem has disappeared

Answer 7

In my case, I had this problem with the image picker, then I followed the documentation and used an emulator with api 29+, it didn't work before because I was using an emulator with api 28 https://pub.dev/packages/image_picker

Answer 8

Uninstalling and installing the app works for me

Answer 9

just open terminal and
step1 flutter clean
step2 flutter pub get
step3 flutter run
Its worked for me,
Thanks have a good day .

Answer 10

i think if you have already done flutter pub get on the dependency, and added all the requirements for the given platform you just have to flutter run your app
