It keep telling setWindowTitle not found during test but all files of test source code are not related with Flutter.

Same here, but on Linux.

You are hitting the issue fixed by https://github.com/flutter/flutter/pull/90288, causing your flutter test to run your application's main.dart instead of the test file. You need to either use Flutter master, or delete generated_main.dart from your .dart_tool directory before running flutter test.

This has nothing to do with this plugin, window_size just happens to be a plugin you are calling early in your application main.
