I am trying to move slider for zoom in flutter camera. I tried many things but I could not get solution. I am attaching my code with screenshot. Please give right suggestion.
double _minAvailableZoom = 2.0;
double _maxAvailableZoom = 2.0;
double _currentZoomLevel = 2.0;
Expanded(
child: Slider(
value: _currentZoomLevel,
max: _maxAvailableZoom,
min: _minAvailableZoom,
activeColor: Colors.white,
inactiveColor: Colors.white30,
onChanged: (value) async {
setState(() {
_currentZoomLevel = value;
});
await cameraController!.setZoomLevel(value);
},
),
),
CodePudding user response:
just do this,
double _minAvailableZoom = 0.0;
double _currentZoomLevel = 0.0;
