Flutter app don't show anything

[shiipou]

Hi, I've build flutter-pi on my raspberry pi with all dependency on the README of the project, but my screen didn't show the flutter app on the raspberry pi. The Flutter app was a fresh new app generated with flutter create launcher and patched with :

import 'package:flutter/foundation.dart'
[...]
debugDefaultTargetPlatformOverride = TargetPlatform.fuchsia;

I can only see my mouse cursor in black on top of my terminal ouput.

Can anyone help me ?

Here all commands I've run on my RPI :

pi@raspberrypi:~ $ history 
    1  raspi-config 
    2  sudo raspi-config 
    3  git clone https://github.com/ardera/flutter-pi

Ok after some investigation of my own, This issue was now fixed.
I've just need to switch back to stable with flutter channel stable and run flutter upgrade.

As a sidenote, the debugDefaultTargetPlatformOverride = TargetPlatform.fuchsia; is no longer necessary, since flutter supports linux out of the box now. It's best to not specify any override at all now.

Ok thank you for the note. That look better for me.
