How to use "libadwaita_bitsdojo"?

[Ridhubharan]

Instructions are not clear. Where am I supposed to put the following(as per https://github.com/gtk-flutter/libadwaita_plugins/tree/main/libadwaita_bitsdojo#usage)?

AdwHeaderBar.bitsdojo(
    appWindow: appWindow,
    ...
)

The 'headerbar' used in the 'AdwScaffold' widget is deprecated. (https://github.com/gtk-flutter/libadwaita_plugins/blob/main/libadwaita_bitsdojo/example/example.md)

Check out this! https://pub.dev/packages/bitsdojo_window#for-linux-apps

Step by step:

1. flutter pub get libadwaita_bitsdojo to install the package
2. in your my_application.cc file, add
   #include <bitsdojo_window_linux/bitsdojo_window_plugin.h>
   to the top of the file, comment out the line
   gtk_window_set_default_size(window, 1280, 720);
   and add

auto bdw = bitsdojo_window_from(window);
bdw->setCustomFrame(true);

directly above it
3. In your main.dart file (your root MaterialApp widget) use AdwScaffold() as your scaffold, example below

return AdwScaffold(
      start: const [AdwHeaderButton(icon: Icon(Icons.abc))],
      actions: AdwActions().bitsdojo,
      body: const Center(
        child: Text('Welcome to Bitsdojo Window Example!'),
      ),
    );

You should now get something like this:

I'll have to make a PR to update the example as I found it was very outdated too!
