idleMilliseconds method

@override int idleMilliseconds()

The Idle duration in milliseconds.

Throws UnsupportedError when isSupported is false. Implementations that are supported must not throw for ordinary OS failures — they report 0 (treat the user as active) so a transient failure cannot silently end monitoring.

Implementation

@override
int idleMilliseconds() => throw UnsupportedError(
      '$name: flutter_inactive_timer reads the idle duration through '
      'platform-specific FFI and supports Windows and macOS only.',
    );
