I have tried a lot with this flutter based app, named snap. But I have still facing several issues with it. This is the current snapcraft.yaml file

But whenever I run this, I get

/snap/saber/19/bin/saber: symbol lookup error: /snap/saber/19/gnome-platform/usr/lib/x86_64-linux-gnu/libpango-1.0.so.0: undefined symbol: hb_ot_layout_get_horizontal_baseline_tag_for_script

If I use the flutter extension the theming will not work perfectly, there will be cursor icon issues & the maximize and minimize button would have gone. Can anyone please help me?
