Flutter Windows App does not start in release mode

Question

I just created a flutter project on Windows with

flutter create appname --platforms=windows,macos

Now I can start this Windows app with

flutter run -d windows

and everything works perfectly. But the problem is that I can not start the Windows app in release mode. I tried:

flutter run --release -d windows

but the app window is not showing up. I just see the process running in the task manager. There is no need to show you the code of the project as it is the template project you get with flutter create. No single line was modified.

The release mode works on every other platforms including web and macos. I also tried to start the .exe file manually but that doesn't work either. I also tried changing to the master version of flutter but it also does not work with the latest master version.

flutter doctor -v does not show any errors:

I had the same issue & I was using a package sqflite_common_ffi and because of that, it wasn't showing up, though it was visible in the task manager only, to resolve this issue I just copied sqlite3.dll to build\windows\x64\runner\Release\ dir, & it fixed my issue!

For anyone wondering what exactly to download

Open that link sqlite3.dll
Then under section Precompiled Binaries for Windows ( I'm using windows)
Select either 32 or 64 link depending on your platform, mine was 64
Then download and extract files
open extracted folder and copy all items inside
Go and paste them inside YourProject\build\windows\x64\runner\Release directory

Then it is done!

This was my issue, thanks. I wouldn't have thought about an extension causing it.

That's what happened to me as well. Thanks!

It works if you edit the windows/runner/flutter_window.cpp like mentioned in @Zensonaton's answer. But I fixed it by adding a restorationScopeId in MaterialApp like this:

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      restorationScopeId: "Test", // <-- Add this line
      home: Scaffold(
        body: Container()
      )
    );
  }
}

Looks like this is a bug with Flutter?

Edit the windows/runner/flutter_window.cpp, replace this line:

flutter_controller_->engine()->SetNextFrameCallback([&]() {
    this->Show();
});

with this:

this->Show();

Source.

I solved a similar problem by running the debugger. There was an error, I fixed it. And secondly, I commented out this line and everything worked. Now not only the process starts, but the Win window itself is displayed. WHY -1 REPUTATION from a BOT??? :(

debugDefaultTargetPlatformOverride = TargetPlatform.fuchsia;  // comment it
