When changes happen to FlutterMap
's internal state (such as a change to the current MapCamera
) it emits a MapEvent
, which can be handled by you.
There's two methods to catch all emitted MapEvent
s. These methods expose the raw MapEvent
, and is recommended in cases where multiple events need to be caught, or there's no more specific callback method available in MapOptions
(see Catching Specific Events).
Listening to a MapController
's mapEventStream
, which exposes events via a Stream
Specifying a callback method in MapOptions.onMapEvent
If only a couple of events need to be caught, such as just an onTap
handler, it is possible to avoid handling the raw Stream
of MapEvent
s. Instead, MapOptions
has callbacks available for the following events:
onTap
onLongPress
onPositionChanged
onPointerDown
/onPointerUp
/onPointerHover
/onPointerCancel
onMapReady
Primarily used for advanced MapController
