Flutter on Fedora 36 - Linux compilation not working "unable to load driver: swrast"

Question

when running flutter run to run on linux, a blank page appears with this in the debug console:

Launching lib/main.dart on Linux in debug mode...
libGL error: MESA-LOADER: failed to open swrast: /lib64/libpthread.so.0: version `GLIBC_PRIVATE' not found (required by /snap/flutter/current/usr/lib/x86_64-linux-gnu/dri/../../../../lib/x86_64-linux-gnu/librt.so.1) (search paths :/usr/lib/dri:/snap/flutter/current/usr/lib/x86_64-linux-gnu/dri:, suffix _dri)
libGL error: failed to load driver: swrast
** (flutter_mastering:4822): WARNING **: 18:51:11.101: Failed to start Flutter renderer: Unable to create a GL context

The issue is because of the snap install, what worked for me is replacing the snap version with the manual install from github. You can also use the tarball.

git clone https://github.com/flutter/flutter.git -b stable

now to add flutter to path:

sudo gedit ~/.bashrc

Assuming ur flutter install was at /home/user/ add this at the end of the file:

export PATH="$PATH:/flutter/bin"

If ur flutter install is somewhere else then change the directory accordingly

After saving and exiting, refresh ur .bashrc file with:

source ~/.bashrc

Now check if its added to path with:

echo $PATH

If you see a /flutter/bin then ur doing fine. To check if flutter's installed:

flutter  --version

To add any missing dependencies (if ur on Fedora) use:

sudo dnf install bash curl file git unzip which xz zip mesa-libGLU clang cmake ninja-build pkg-config gtk3-devel

On Ubuntu based distros it is

sudo apt-get install clang cmake ninja-build pkg-config libgtk-3-dev liblzma-dev
