1681-engine / mobile / BackStack

Class: BackStack

Defined in: src/mobile/backButton.ts:10

Who answers Android's back button (and the back gesture): the most recently pushed handler first, then the ones under it, then onRoot when none took it. A dialog pushes "close me" when it opens and pops it when it closes; a pause menu pushes "resume"; the title screen leaves the press to onRoot, which by default asks for a second press to quit, so a stray swipe never ends a run.
