DrawerManager class
A drawer container that has the ability to swap Scaffold body contents, using a custom provider.
A Drawer Manager is similar to the Android Drawer, in that it swaps out Widgets (like Android Fragments). It does this by notifying the Scaffold body of the changes needed for your selection using the DrawerManagerProvider's body property.
Similar to Flutter's TextEditingController, the Drawer Manager uses Provider's ChangeNotifier as a parent class to manage user selection by displaying the Widget selection. This happens in the DrawerManagerProvider.selectDrawer method, and it basically returns from a list of onTap functions the position that was tapped. Then it uses that positin to set the current drawer selection, and notifies the Drawer Manager's body property and any other Consumers to make the update for this drawer selection.
The selections can be more than the Drawer Tiles, but the tiles can not be more than the selections.
const drawerSelections = [
HelloPage(),
CounterPage(),
TheMACPage()
];
Here is an example of a DrawerManager with drawerElements and drawerSelections added.
drawer: DrawerManager(
context: context,
drawerElements: [
const DrawerHeader(
child: Padding(
padding: EdgeInsets.only(bottom: 20),
child: Icon(Icons.account_circle),
),
),
DrawerTile(
context: context,
leading: const Icon(Icons.hail_rounded),
title: Text('Hello'),
onTap: () async {
// RUN A BACKEND Hello, Flutter OPERATION
},
),
// ...
],
tileSelections: drawerSelections
)
