A simple Flutter plugin to manage the device torch / flashlight.
import 'package:torch_light/torch_light.dart';
try {
final isTorchAvailable = await TorchLight.isTorchAvailable();
} on Exception catch (_) {
// Handle error
}
Enable and disable the device torch / flash:
try {
await TorchLight.enableTorch();
} on Exception catch (_) {
// Handle error
}
try {
await TorchLight.disableTorch();
} on Exception catch (_) {
// Handle error
}
If you want further control over the errors, you can declare explicit exceptions:
// Enable torch and manage all kind of errors
try {
await TorchLight.enableTorch();
} on EnableTorchExistentUserException catch (e) {
// The camera is in use
} on EnableTorchNotAvailableException catch (e) {
// Torch was not detected
} on EnableTorchException catch (e) {
// Torch could not be enabled due to another error
}
// Disable torch and manage all kind of errors
try {
await TorchLight.disableTorch();
} on DisableTorchExistentUserException catch (e) {
// The camera is in use
} on DisableTorchNotAvailableException catch (e) {
// Torch was not detected
} on DisableTorchException catch (e) {
// Torch could not be disabled due to another error
}
