Question: release with Raspberry4 support?

[apiraino]

Hi!

I'm trying to run the release binary from november 2019, I get this error:

pi@raspberrypi:~ $ ./flutter-pi -m /dev/input/event0 -t /dev/input/event0 flutter_gallery_assets/flutter_assets/ -r 90
Using mouse input from mouse /dev/input/event0
Using touchscreen input from /dev/input/event0
Asset bundle path: flutter_gallery_assets/flutter_assets/
engine_argv[0] = ./flutter-pi
engine_argv[1] = -r
engine_argv[2] = 90
initializing display...
Opening DRM device...
Getting DRM resources...
/dev/dri/card0 doesn't look like a modeset device

Possibly the binary still does not support the Rpi4 (possibly related to this issue) and I have to manually compile, correct?

I have run all the steps to build the Flutter app assets, app.so and downloaded the engine binaries from this branch.

I have customized the raspi according to your instructions.

thanks for your project 👍

@apiraino did you try to compile the latest master? there is a make file :)

The november 2019 is very very outdated. It doesn't support the Pi 4 and it also doesn't support rotation. (-r 90).

But be aware that the invocation is flutter-pi <flutter-pi options> <asset bundle path> <flutter engine options>. So even if your flutter-pi was latest master, the -r 90 argument would not be recognized since you specified it as a flutter engine option, after the asset bundle path. It's a flutter-pi option though, so it needs to be before the asset bundle path. The flutter-pi options are the ones listed in the usage. flutter engine options are the ones you can find in the switches.cc file (link in the usage), for example --observatory-host, --observatory-port

The november 2019 is very very outdated. It doesn't support the Pi 4 and it also doesn't support rotation. (-r 90).

I've managed to build flutter-pi from master branch and I can launch the flutter gallery sample application (although it seems to work intermittently, but this is another issue I will try to figure out some other time).

This question can then be closed, thanks!
