bindMainScaffoldKey method
Explicitly binds the ScaffoldState used by main drawer helpers.
Main-stack drawer helpers auto-bind to the current page when possible. Use this method only when you want to override that behavior.
Implementation
void bindMainScaffoldKey(GlobalKey<ScaffoldState> scaffoldKey) {
if (isMainStack) {
_mainScaffoldKey = scaffoldKey;
} else {
debugPrint(
'Warning: bindMainScaffoldKey() should only be called on main stack');
}
}
