packages/flutter/lib/src/material/menu_anchor.dart

        hasSubmenu: false,
        overflowAxis: _anchor?._orientation ?? widget.overflowAxis,
-        child: widget.child!,
+        child: widget.child ?? const SizedBox(),


Using const SizedBox.shrink(); Would be better.

@mahmoudsaleh1997 Agreed, thank you

packages/flutter/lib/src/material/menu_anchor.dart

        hasSubmenu: false,
        overflowAxis: _anchor?._orientation ?? widget.overflowAxis,
-        child: widget.child!,
+        child: widget.child ?? const SizedBox.shrink(),


Rather than just a one-line change here, would you be able to update _MenuItemLabel so it has a nullable child property? Currently it's still documented as being required:

const _MenuItemLabel({ required this.hasSubmenu, this.showDecoration = true, this.leadingIcon, this.trailingIcon, this.shortcut, this.semanticsLabel, this.overflowAxis = Axis.vertical, required this.child, }); /// The required label child widget. final Widget child;

@nate-thegrate Thank you for your review，i have updated~

      );
    });
+
+    testWidgets('MenuItemButton is null check operator when it child is null', (WidgetTester tester) async {


Suggested change

testWidgets('MenuItemButton is null check operator when it child is null', (WidgetTester tester) async {

testWidgets('MenuItemButton can build when its child is null', (WidgetTester tester) async {

The rest of this test looks fantastic!

@nate-thegrate Thank you for your review，i got it~
