How to fix this error?

Solution 1

ThreadedInputConnectionProxyAdapterView has wrong extension .jav just change it to .java until the flutter team release the fix.

Please refer to the github link for the issue

Solution 2

As Ravi stated, renaming the file extension to .java does the trick.

The file can be found at:

{your flutter folder}\.pub-cache\hosted\pub.dartlang.org\webview_flutter-2.0.6\android\src\main\java\io\flutter\plugins\webviewflutter\ThreadedInputConnectionProxyAdapterView.java
