flutter iOS有白屏

Question

I run my app on the simulator and keep getting a white screen. While the same works on an android simulator.

I'm not able to find a reason in the logs.

user:$ flutter run

Answer 1

as suggested by @pskink using --enable-software-rendering works.

flutter run --enable-software-rendering

Answer 2

1- rm -rf ios/Flutter/App.framework

2- Change the Runner target build settings Build Phases > Thin Binary script as follows:

/bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" embed
/bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" thin

Answer 3

I faced the same issue. Try to upgrade flutter to the latest.

flutter upgrade

then clean the project.

flutter clean

Try running again
