How to use expo-brightness - 10 common examples

return async () => {
      await Brightness.setBrightnessAsync(value);
      this.updateBrightness();
    };
  }

function setBrightness(brightness: number) {
		return setBrightnessAsync(brightness).then(() => setData(brightness));
	}

_brightness = async () => {
    if (!this.state.brightness) {
      await Brightness.setBrightnessAsync(1);
    } else {
      await Brightness.useSystemBrightnessAsync();
    }
    this.state.brightness ? this.setState({ brightness: false }) : this.setState({ brightness: true });
  }

return async () => {
      await Brightness.setSystemBrightnessAsync(value);
      this.updateBrightness();
    };
  }

(async () => {
      const { status } = await Brightness.requestPermissionsAsync();
      if (status === 'granted') {
        Brightness.setSystemBrightnessAsync(1);
      }
    })();
  }, []);

private async updateBrightness() {
    this.setState({
      normalBrightness: await Brightness.getBrightnessAsync(),
      systemBrightness: await Brightness.getSystemBrightnessAsync()
    });
  }
}

function getBrightness() {
		return getBrightnessAsync().then(setData);
	}

This example uses both the Permissions and Brightness modules.
				When you grant the SYSTEM_BRIGHTNESS permission, it renders two buttons to switch the system brightness mode.
			
			
				{(permission && permission.status !== 'granted') && (
					
						We need permission to modify the system brightness.
					
				)}
				{(permission && permission.status === 'granted') && (
					<>
						
							<button mode="{mode" color="#333"> setMode(BrightnessMode.AUTOMATIC)}
							&gt;
								Automatic
							</button>
						
						
							<button mode="{mode" color="#333"> setMode(BrightnessMode.MANUAL)}
							&gt;
								Manual
							</button>
						
					
				)}

								onPress={() => setMode(BrightnessMode.AUTOMATIC)}

								onPress={() => setMode(BrightnessMode.MANUAL)}
