I have same question.

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

hacjy commented 2 years ago

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

shenlanchenwei commented 2 years ago

The namespace is not "com.fluent webview Plugin", it should be "-keep class com.flutter_webviewplugin.* { ; }" ^^
