I am developing an android mobile application side by side (no emulator). Hot reloading doesn't work because the vm service doesn't start as for why I have no idea. Hot reloading works in a fresh new flutter project. Flutter doctor does not indicate any errors. This is also on a Linux system (Arch).

Here's the output from flutter run -v, pasted below.

I have disabled firewalls and I found another thread asking to add <uses-permission android:name="android.permission.INTERNET"/> to the manifest but it's already there.

I've tried rolling back to the first commit by a git reset to the starting point of the flutter project and it still doesn't work. Cleaned the build files and flutter as well by running flutter clean, flutter pub get, & flutter run.

Sorted by: Reset to default 0

Fixed the issue by manually enabling network permissions to the app in application, it was disabled by default for some reason. Maybe it is a security thing in Lineage OS or Android it self.
