How to get rid of GoRouter initial route builder method always being called inbetween navigations

Question

My app_router.dart looks like this

GoRoute(
      path: '/',
      name: AppRoute.todoList.name,
      redirect: (context, state) async {
        var initialRoute = await getInitialRoute();
        return initialRoute != AppRoute.todoList.name ? "/$initialRoute" : null;
      },
      builder: (context, state) => TodoListScreen(),
      routes: [
        GoRoute(
            path: 'add',
            name: AppRoute.todoAdd.name,
            builder: (context, state) => TodoAddScreen()),
        GoRoute(
            path: 'edit/:id',
            name: AppRoute.todoEdit.name,
            builder: (context, state) {
              final todoId = state.pathParameters['id']!;
              return TodoEditScreen(todoId: int.parse(todoId));
            })
        ]
    )

The problem I have is that whenever I navigate to add or edit for example, TodoListScreen() builds its entire widget tree again (after the add, edit widget tree has been built). I.e. it builds the TodoListScreen widget again, it does this even when I navigate into child widgets of add and edit This is causing issues for me data retention-wise.

AppRoute is just an enum

Is this by design when using goRouter? If not can someone help me refactor this?

Thanks in advance!
