I face this problem when I use better_player in flutter, It was work good but now show this problem .
Any one can help me
I have a method thats called to load models but seems to crash every time I call it, I followed the documentation for it I believe so I dont understand why.
Future loadModel() async {
await FirebaseModelDownloader.instance
.getModel(
"Breed-Detector",
FirebaseModelDownloadType.latestModel,
FirebaseModelDownloadConditions(
iosAllowsCellularAccess: true,
iosAllowsBackgroundDownloading: false,
androidChargingRequired: false,
androidWifiRequired: false,
androidDeviceIdleRequired: false,
))
.then((customModel) async {
final localModelPath = customModel.file;
Tflite.close();
String res;
res = (await Tflite.loadModel(
model: localModelPath.toString(), labels: "assets/labels.txt"))!;
print("Models Loading status: ${res}");
});
}
I get the error

I have implemented flutter_sslcommerz plugin on my project. It works well on my emulator while debugging, but it doesn't seem to work while tested on a physical device.
I called the SSLCommerzInitialization function placing the necessary parameters.
Here is the error below -

Thanks a lot for every little help.
Map shows fine, but does not show marker.
When you add a new marker when map finished loading and idling, the marker shows.
When you add a delay to addSymbol inside "onMapCreated" like below, it then shows the symbol:
Future.delayed(Duration(milliseconds: 1500), () {
mapController.addSymbol(
SymbolOptions(
geometry: LatLng(widget.post.lat, widget.post.long),
iconImage: "airport-15",
iconSize: 5,
),
);
});
How do we know or are suppose to handle the wait for onStyleCallBack?
This is the error that comes up when you don't add the delay:
Attempt to invoke virtual method 'java.util.List com.mapbox.mapboxsdk.plugins.annotation.SymbolManager.create(java.util.List)' on a null object reference
Works perfectly on iOS without any delays.
Same behaviour on device and emulator.
Version: mapbox_gl: ^0.9.0
Code:
onMapCreated: (MapboxMapController controller) async {
controller.addSymbol(
SymbolOptions(
geometry: LatLng(widget.post.lat, widget.post.long),
iconImage: "airport-15",
iconSize: 5,
),
);
},

Please note: you should only add annotations (e.g. symbols or circles) after onStyleLoadedCallback has been called. So you should add symbols inside onStyleLoadedCallback callback.
Maybe is later but I just wanna post answer because there are some few answers about it ...
Like Edwin Triviños says, you just need to set your callback on MapBox parameters and create a new function to do whatever you wanna do. For example, in my case:
Mapbox config:
return MapboxMap(
accessToken: MapboxVariables.accessToken,
styleString: "mapbox://styles/your-url-from-mapbox",
onMapCreated: _onMapCreated,
onStyleLoadedCallback: _onStyleLoaded,
zoomGesturesEnabled: true,
myLocationEnabled: true,
trackCameraPosition: true,
myLocationTrackingMode: MyLocationTrackingMode.Tracking,
onUserLocationUpdated: (UserLocation userLocation){
_movingCameraToLocation();
},
initialCameraPosition: const CameraPosition(
target: LatLng(-33.852, 151.211),
zoom: 11.0,
),
);
As you can see, I'm calling onStyleLoadedCallback: _onStyleLoaded, as a callback. An after that just need a basic _onStyleLoaded function, like this:
void _onStyleLoaded() async {
//your code
}
