Using FlutterAdaptiveScaffold with GoRouter

I set out to answer my own question posed to the StackOverflow community:

The definition of done is as follows:

1 - On the top row, the wide layout is presented, whereas the bottom row shows the narrow layout. In both cases, the flow is:

• No navigation state
• Navigation item selected
• Item selected in list

2 - The URI for each step is as follows:

• /
• /nav1
• /nav1/2

This solution solves each of these problems and meets the definition of done. However, there is still room for improvement. Pull requests are welcome.
