Flutter web view doesn't work on release mode

Question

I'm creating a Flutter application.

If I run this application on debug mode webview works well

but if I run this application on release mode it shows blank screen. It's showing PlatformException

I tried to get help from github issues but couldn't find the solution.

Manifest

<uses-permission android:name="android.permission.INTERNET"/>

build.gradle

minSdkVersion 20
targetSdkVersion 29

pubspec.yaml

webview_flutter: ^1.0.7

Solution

Please check for "android.permission.INTERNET" pemission in your Manifest file. In "app/src/main/AndroidManifest.xml" folder. I use flutter_inappwebview: ^5.3.2 plugin and faced same issue in release mode.
