setAlpha method

  1. @override
bool setAlpha(
  1. double alpha
)
override

Method is used to set the opacity of the map object. alpha Opacity multiplier. Values below 0 will be set to 0. Values above 1 will be set to 1. Default: 1. Returns true if the operation is successful, false otherwise.

Example:

// Set alpha transparency
bool alphaSuccess = _circleMapObject!.setAlpha(0.7);
print("Set circle alpha to 0.7: $alphaSuccess");

Implementation

@override
bool setAlpha(double alpha) {
    final _setAlphaFfi = __lib.catchArgumentError(() => __lib.nativeLibrary.lookupFunction<
        Uint8 Function(Pointer<Void>, Float),
        int Function(Pointer<Void>, double)
      >('navigine_sdk_flutter_MapObject_setAlpha__Alpha'));
    final _alphaHandle = navigine_sdk_flutter_double_ToFfi(alpha);
    final _handle = this.handle;
    final __resultHandle = _setAlphaFfi(_handle, _alphaHandle);
    navigine_sdk_flutter_double_ReleaseFfiHandle(_alphaHandle);
    final _result = navigine_sdk_flutter_bool_FromFfi(__resultHandle);
    navigine_sdk_flutter_bool_ReleaseFfiHandle(__resultHandle);
    return _result;
}
