window losing response caused by MoveWindow #77034
Description
Use Flutter's DEV branch and win32 plug-in.In windows desktop projects, the window loses its response when the MoveWindow function of win32 is called directly from the Flutter interface. It is suspected WM_SIZE the modification of the sub-window in the message.
The 1.26.0-12.0.pre version of flutter does not have this problem.
After the flutter is updated to the latest version (DEV or 1.27.0-4.0pre), the program stops responding after modifying the window size through MoveWindow or SetWindowPos interface.
I raised this issue in the win32 plug-in project, and it has been agreed that this is not a win32 plug-in issue.
(halildurmus/win32#157)
I found a solution. By modifying the (windows\runner\win32_window.cpp) file, create a custom message that delays the code WM_SIZE the modified sub-window.
(#76973)
This is the test project I wrote, please note that the latest submission contains the solution.
