Methods
-
disableTorch(
) → Future< void> - Disables the torch.
-
enableTorch(
{FlashMode mode = FlashMode.torch}) → Future< void> -
Enables the torch with specified flash mode.
mode- The flash mode to use (torch or flash). -
getCapabilities(
) → Future< TorchCapabilities> - Returns the capabilities of the torch on the current platform.
-
getCurrentTorchStrength(
) → Future< int> - Returns the current torch strength level. Returns 0 if not supported or torch is off.
-
getMaxTorchStrength(
) → Future< int> - Returns the maximum torch strength level supported by the device. Returns 0 if not supported.
-
isTorchAvailable(
) → Future< bool> - Checks if the torch is available on the device.
-
isTorchOn(
) → Future< bool> - Returns the current torch state (true if on, false if off).
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
setTorchStrength(
int strength) → Future< void> -
Sets the torch strength level.
strengthshould be between 0 and getMaxTorchStrength(). Throws an error if not supported by the device. -
startForegroundService(
) → Future< void> - Starts foreground service for background torch operation (Android only). Required for torch to continue working when app is in background.
-
startNativeBlink(
int interval) → Future< void> -
Starts native periodic blinking for better performance.
interval- The interval between on/off toggles in milliseconds. -
stopForegroundService(
) → Future< void> - Stops foreground service (Android only).
-
stopNativeBlink(
) → Future< void> - Stops native periodic blinking.
-
toString(
) → String -
A string representation of this object.
