Try to set the BackgroundColor of shell to White, it would hide the hamburger icon.
<Shell
....
BackgroundColor="White"
....>
Or you could use the custom renderer to reset the toolbar background color to white. It would hide the icon as well.
[assembly: ExportRenderer(typeof(AppShell), typeof(MyShellRenderer))]
namespace ShellDemo2.Droid
{
public class MyShellRenderer : ShellRenderer
{
public MyShellRenderer(Context context) : base(context)
{
}
protected override IShellToolbarAppearanceTracker CreateToolbarAppearanceTracker()
{
return new MyToolbarAppearanceTracker(this);
}
protected override IShellTabLayoutAppearanceTracker CreateTabLayoutAppearanceTracker(ShellSection shellSection)
{
return new MyTabLayoutAppearanceTracker(this);
}
}
public class MyToolbarAppearanceTracker : IShellToolbarAppearanceTracker
{
private MyShellRenderer myShellRenderer;
public MyToolbarAppearanceTracker(MyShellRenderer myShellRenderer)
{
this.myShellRenderer = myShellRenderer;
}
public void Dispose()
{
}
public void ResetAppearance(Android.Support.V7.Widget.Toolbar toolbar, IShellToolbarTracker toolbarTracker)
{
toolbar.SetBackgroundColor(Android.Graphics.Color.White);
}
public void SetAppearance(Android.Support.V7.Widget.Toolbar toolbar, IShellToolbarTracker toolbarTracker, ShellAppearance appearance)
{
}
}
}
