I have same question.

Android obfuscation program causes this problem, closing it can solve this problem

Thank you ! @shenlanchenwei
Turn off obfuscation or add the code "- keep class com.fluent_ webview_ Plugin. * * {*;}" in the obfuscation file, this problem is solved.

The namespace is not "com.fluent_ webview_ Plugin", it should be "-keep class com.flutter_webview_plugin.** { *; }"
