MissingPluginException while using plugin for flutter

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 :

just open terminal and

Step1
Delete all the temporary file generated during the build process this is by removing the build/ directory by running this command
flutter clean

Step 2
After deleting your build/ directory run this command to fetch and download dependencies indicated in your pubspec.yaml file
flutter pub get

Step 3 This command builds and runs your application to a connected device or environment of choice, is to validate if everything is working as expected.
flutter run

Its worked for me, Thanks have a good day .

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

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.

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

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

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.
