I'm following https://flutter.dev/docs/development/add-to-app/ios/project-setup to add flutter into ios app with Option B. but i found sample from https://github.com/flutter/samples/tree/master/add_to_app is not Option B(Embed frameworks in Xcode)

Steps

I tried to do it with following steps.

ios_fullscreen.zip

  1. remove codes refer to Option A
  2. cd fluttter_module and run flutter build ios-framework
  3. drag App.framework and Flutter.framework from debug folder to Embedded Binaries
    tmp7734a81e
    4.run ios_fullscreen
    5.attach flutter using vscode 'Debug:Attach to Fllutter Process '

Problem

1.can't hit breakpoint only if click reconnect
2.when i change codes and try to hot reload, it was crashed.

Can we get the full crash log? I can't tell what is EXC_BAD_ACCESS (probably some overreleased object?).

Reproduce, then attach the crash log with the right timestamp from:
Xcode > Window > Devices and Simulators > your device > View Device Logs

Is Flutter.framework and App.framework in the same directory as your IOSFullScreen.xcodeproj? It's not present in the zip.
