CodePudding user response：

As mentioned above, you can use titleview, or you can create a custom renderer for NavigationPage instead of Page , and override the OnLayout method . Related Document:https://docs.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/custom-renderer/

Android will change the detault icon back in UpdateToolbar method , and OnLayout method is triggered every time while current page is changed.

On Android:

[assembly: ExportRenderer(typeof(NavigationPage), typeof(MyNavigationRenderer))]
namespace FormsApp.Droid
{
    public class MyNavigationRenderer : NavigationPageRenderer
    {
        Context _context;

        AndroidX.AppCompat.Widget.Toolbar _toolbar;

        public MyNavigationRenderer(Context context) : base(context)
        {
            _context = context;
        }

        public override void OnViewAdded(Android.Views.View child)
        {
            base.OnViewAdded(child);
            if (child.GetType() == typeof(AndroidX.AppCompat.Widget.Toolbar))
            {
                _toolbar = (AndroidX.AppCompat.Widget.Toolbar)child;
                _toolbar.SetNavigationIcon(Resource.Drawable.bbutton_nav);
            }
        }

        protected override void OnLayout(bool changed, int l, int t, int r, int b)
        {
            base.OnLayout(changed, l, t, r, b);

            if (_toolbar != null)
            {
                if (_toolbar.NavigationIcon != null)
                {
                    _toolbar.NavigationIcon = AndroidX.Core.Content.ContextCompat.GetDrawable(_context, Resource.Drawable.bbutton_nav);
                }
            }
        }
    }
}

On Ios:

[assembly: ExportRenderer(typeof(NavigationPage), typeof(MyRenderer))]
namespace FormsApp.iOS
{
    class MyRenderer : NavigationRenderer
    {
        public override void ViewDidLayoutSubviews()
        {
            base.ViewDidLayoutSubviews();

          
            if (this.NavigationBar.TopItem.BackBarButtonItem == null)
            {
                this.NavigationBar.BackIndicatorImage = UIImage.FromFile("pic.png");
                this.NavigationBar.BackIndicatorTransitionMaskImage = UIImage.FromFile("pic.png");
                this.NavigationBar.TopItem.BackBarButtonItem = new UIBarButtonItem("Dashboard", UIBarButtonItemStyle.Plain, null);
            }
        }

    }
}
