How do I run some flutter example? #17

Closed james-bay closed 3 years ago

james-bay commented 3 years ago

Can you please tell me how to run some example? I tried to make a bundle as described in https://github.com/ardera/flutter-pi However, it did not work that way:

root@raspberrypi4-64:~# flutter_wayland ~/my_app 
LOG: /usr/src/debug/flutter-wayland/git-r0/git/src/main.cc:61: Arg: /home/root/my_app
error: XDG_RUNTIME_DIR not set in the environment.
terminate called after throwing an instance of 'std::runtime_error'
Bus error

If you're logged in as root: export XDG_RUNTIME_DIR=/run/user/0 export WAYLAND_DISPLAY=wayland-0

Thank you! Unfortunately I ran into another problem:

If you built flutter-engine then on target cp /usr/share/flutter/icudtl.dat to /usr/bin/

Keep in mind flutter_wayland is a proof of concept, and not a full-featured embedder. It's recommended you write your own embedder to meet your needs.

@jwinarske thank you for help!

jwinarske commented 3 years ago

I've added recipes back in for Flutter Gallery and Flutter SDK. The Gallery recipe generates an AOT image.

This may help or confuse things :) I will add more in the way of documentation soon.

jwinarske commented 3 years ago

Let me know if there is something you would like me to add to the README.md, otherwise I will close this issue.

jwinarske commented 3 years ago

closing since I just opened up discussions
