Takes an integer bitfield, which can be treated similar to enumerables. For example:
InteractiveFlag.all & ~InteractiveFlag.rotate
allows/enables all interactions except for rotation (keeping the map at the heading specified by
rotation).The flags below are available:
Flag | Description |
|---|---|
all | Enables all interactions |
none | Disables all interactions |
drag | Enables panning with one finger |
pinchMove | Enables panning with two or more fingers |
flingAnimation | Enables fling animation when drag/pinchMove have enough 'Fling Velocity' |
pinchZoom | Enables zooming with a pinch gesture |
doubleTapZoom | Enables zooming with a double tap (prevents onTap from firing) |
rotate | Enables rotating the map with a twist gesture |
Use
& for 'AND' logic and ~ for 'NOT' logic. Combining these two gates, as shown in the example, can lead to many combinations, each easy to put together.Defaults to enabling all interactions (
all).Used together to enable scroll wheel scrolling, and set it's sensitivity/speed.
The first parameter takes a
bool, enabling or disabling scroll wheel zooming. The second takes a double, which is used as a multiplier for changing the zoom level internally. enableScrollWheel: true,
scrollWheelVelocity: 0.005,
Defaults to
true and 0.005.Takes a function with two arguments. Gets called whenever the map position is changed, even if it is not changed by the user.
onPositionChanged: (MapPosition position, bool hasGesture) {
// Your logic here. `hasGesture` dictates whether the change
// was due to a user interaction or something else. `position` is
// the new position of the map.
}
Takes a function with one argument. Gets called whenever the the user taps/clicks/presses on the map.
onTap: (TapPosition position, LatLng location) {
// Your logic here. `location` dictates the coordinate at which the user tapped.
}
This callback can be registered if you need to do something with the map controller as soon as the map is available and initialized; generally though it isn't needed and the map is available after first build.
Takes a function with zero arguments. Gets called from the
initState() method of the FlutterMap.Last modified 10d ago
