Classes

BackAppDied

The app process died while fdb was communicating with it.

BackAtRoot

Nothing in the app handled the back press (already at the root screen).

BackError

Generic / unrecognised error.

BackNoHelper

fdb_helper was not detected in the running app.

BackPopped

The app handled the back press: a route was popped, or a PopScope intercepted it.

BackResult

Result of a navigateBack invocation.

BackUnexpectedResponse

The VM service returned an unexpected response shape.

BackVmError

The VM service returned an error message.

Functions

navigateBack(BackInput _) → Future<BackResult>

Presses the system back button in the running Flutter app, the same way the Android back button does (fdb_helper injects the engine's popRoute).

Typedefs

BackInput = ()

Input parameters for navigateBack. Empty record because fdb back takes no arguments today.
