Description

Description

I have faced these issues while trying to bind icon to IconImageSource of MenuFlyoutItem:

  • Binding does not work with glyph.
  • Binding IconImageSource works only on the first time and does not updates on runtime.

Steps to Reproduce

  1. Create a .net MAUI project
  2. Add a MenuBarItem on xaml/codebehind
  3. Add Binding on the IconImageSource property of a MenuFlyoutItem
  4. Change the icon that is used for binding through a click event

Expected: Icon on MenuFlyoutItem should be updated.

Research direction
Investigate the MenuFlyoutItem implementation in dotnet/maui, specifically the binding of IconImageSource. Check if the property uses BindableProperty correctly and if the binding is re evaluated when the source changes. Refer to the reproduction project at https://github.com/shahadatshakil/MenuItemIconTest for steps. Look for similar issues or PRs related to MenuFlyoutItem binding.
