How to dispose() the better_player when initialization

When opening a new page, the player continues to play this happens when I open another page at the moment the player is initializing

Tried to dispose

• when the focus on the widget disappeared
• when the button was pressed
• when the screen goes out of view

none of this helps

Solution. At the moment the player is initialized, I block the route, after initialization I remove the lock and then you can go to another page by deleting the player.
