Hi!, I'm newer of flutter, I clone the whole project and can not find the code of drawer item click.

I want some working code to learn how drawer item click, can any body help me ?

that would be very help for me! THANKS!!!

Multiple scroll elements were causing the ScrollController error like "The provided ScrollController is currently attached to more than one ScrollPosition"

Added a nice loading animation when flutter loads the js.

Describe the bug The bug occurs when trying to change the body widget or even when trying to navigate to a new screen.

It happens that when changing the Dashboard body widget for another body widget, for example Transactions, the site breaks and does not render correctly the Sidebar and Header area.

Here is a short video example of the problem:

To Reproduce Steps to reproduce the behavior:

1. Change widget of body Dashboard for any other with StreamBuilder or Navigator

Code of MainScreen

class MainScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      key: context.read<MenuController>().scaffoldKey,
      drawer: SideMenu(),
      body: SafeArea(
        child: Row(
          crossAxisAlignment: CrossAxisAlignment.start,
          children: [
            if (Responsive.isDesktop(context))
              Expanded(
                child: SideMenu(),
              ),
            Expanded(
              flex: 5,
              child: StreamBuilder<Widget>(
                stream: outGetWidget,
                builder: (context, w) {
                  if(w.connectionState == ConnectionState.waiting || w.data == null) return const Center(child: CircularProgressIndicator(),);
                  return w.data!;
                },
              ),
            ),
          ],
        ),
      ),
    );
  }
}

All other codes are original for the scripts, the bug is only i change the widget of body.

I tested several alternatives to try to fix this problem, but nothing went right. How do I navigate multiple screens responsively? Apparently it's only usable for a single screen.

flutter run -d chrome

══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY ╞═════════════════════════════════════════════════════════ The following assertion was thrown during performLayout(): RenderFlex children have non-zero flex but incoming height constraints are unbounded. When a column is in a parent that does not provide a finite height constraint, for example if it is in a vertical scrollable, it will try to shrink-wrap its children along the vertical axis. Setting a flex on a child (e.g. using Expanded) indicates that the child is to expand to fill the remaining space in the vertical direction. These two directives are mutually exclusive. If a parent is to shrink-wrap its child, the child cannot simultaneously expand to fit its parent. Consider setting mainAxisSize to MainAxisSize.min and using FlexFit.loose fits for the flexible children (using Flexible rather than Expanded). This will allow the flexible children to size themselves to less than the infinite remaining space they would otherwise be forced to take, and then will cause the RenderFlex to shrink-wrap the children rather than expanding to fit the maximum constraints provided by the parent. If this message did not help you determine the problem, consider using debugDumpRenderTree(): https://flutter.dev/debugging/#rendering-layer http://api.flutter.dev/flutter/rendering/debugDumpRenderTree.html The affected RenderFlex is: RenderFlex#815cd relayoutBoundary=up33 NEEDS-LAYOUT NEEDS-PAINT NEEDS-COMPOSITING-BITS-UPDATE(creator: Column ← RepaintBoundary ← CustomPaint-[GlobalKey#62255] ← MouseRegion ← Listener ← _GestureSemantics ← RawGestureDetector ← RepaintBoundary ← NotificationListener ← NotificationListener ← _MaterialScrollbar ← Scrollbar ← ⋯, parentData: (can use size), constraints: BoxConstraints(w=582.3, 0.0<=h<=Infinity), size: MISSING, direction: vertical, mainAxisAlignment: start, mainAxisSize: min, crossAxisAlignment: center, verticalDirection: down) The creator information is set to: Column ← RepaintBoundary ← CustomPaint-[GlobalKey#62255] ← MouseRegion ← Listener ← _GestureSemantics ← RawGestureDetector ← RepaintBoundary ← NotificationListener ← NotificationListener ← _MaterialScrollbar ← Scrollbar ← ⋯ The nearest ancestor providing an unbounded width constraint is: _RenderSingleChildViewport#7008e relayoutBoundary=up16 NEEDS-LAYOUT NEEDS-PAINT NEEDS-COMPOSITING-BITS-UPDATE: needs compositing creator: _SingleChildViewport ← IgnorePointer-[GlobalKey#9d247] ← Semantics ← Listener ← _GestureSemantics ← RawGestureDetector-[LabeledGlobalKey#9c75f] ← Listener ← _ScrollableScope ← _ScrollSemantics-[GlobalKey#975b4] ← NotificationListener ← RepaintBoundary ← CustomPaint-[GlobalKey#81613] ← ⋯ parentData: (can use size) constraints: BoxConstraints(w=908.0, 0.0<=h<=953.0) size: MISSING offset: Offset(0.0, -0.0)

I downloaded the zip and ran the project It was good but then I added something in pubspec.yaml and then this error popup.
