Flutter web Navigator forward button

Question

My problem

This problem is about Flutter web's navigation. When working with the onGenerateRoute function, the navigation on the web is "near" the vanilla experience. We can pop route with the back button of the browser, push a new route and get those routes' names in the URL. But my problem resides in the forward button:

• When going back on the browser, we can't go forward afterward. (not that bad)
• When you enter a URL for a route manually, we go on this route, but the forward button is enabled, and when click, another same route is pushed in the route stack. (The biggest problem)

Solution

Does someone have the solution to include and fix the forward button in Flutter or a way to disable the forward button completely in the browser?
