About The Project

Brightness service aims to provide an interface where developers are able to create dynamic content based on the brightness of their app, allowing them to go far beyond a simple theme change.

It also includes an easy way for direct access to an android devices light sensor

Gif Example

Getting Started

Installation

Simply ensure that you have CrossBrightnessService.Current.Active = true; with the package installed in both the Shared Platform and iOS/Android

Usage

To get the above effect, i used this code snippet

CrossBrightnessService.Current.Active = true;
CrossBrightnessService.Current.Attach(() =>
{
  var LocalBackgroundColour = Color.Green;
  LocalBackgroundColour = LocalBackgroundColour.AddLuminosity(CrossBrightnessService.Current.CheckBrightness());
  LocalBackgroundColour = LocalBackgroundColour.WithLuminosity(CrossBrightnessService.Current.CheckBrightness());
  LocalBackgroundColour = LocalBackgroundColour.WithHue(CrossBrightnessService.Current.CheckBrightness());
  LocalBackgroundColour = LocalBackgroundColour.WithSaturation(CrossBrightnessService.Current.CheckBrightness());
  BackgroundColour = LocalBackgroundColour;
});

Thats it! For a quick explainer on the details, read on

Plugin.BrightnessService allows access through the IBrightnessService interface, which has the following members/functions available

public List<Action> TickActions { get; set; }

This is the TickActions that will be executed in parallel on a timed basis, with the timing depending on MillisecondResolution. All Functions are invoked on the main thread. While direct access through the setter is possible, it is recommended you use Attach, Attached and OverWriteFunctions for changing its values

public double MillisecondResolution { get; set; }

This is the speed in which the timer will wait before executing TickActions in parallel. While direct access through the setter is possible, it is recommended you use OverwriteRefreshResolution for changing its value

public bool Active { get; set; }

This determines if the timer is active or not.

public bool AndroidLightSensorDirect { get; set; }

This determines if Android will use the screenbrightness of the device (safe), or the direct readouts from the light sensor (be prepared for calibration difficulties.).

public event Action BrightnessResolveTick;

This is what is invoked by the timer. Feel free to attach other things to run on the exact same timing as the brightness service. However, this also serves for how the tickactions get executed. care recommended.

public double CheckBrightness();

This provides the brightness readout. if not using the Android direct light sensor, will be within 0-255

public bool BrightnessChanged();

Provides a more manual approach to checking brightness. First call will 'set' the last brightness each subsequent call will check against the last brightness recorded against the current light reading, if it is different, it will return true and update the last brightness to the current light reading

public List<Action> Attached();

Returns all functions attached and running on TickActions

public void Attach(Action brightnessServiceFunction);

Attaches a new function ontop of TickActions, briefly stopping and restarting the timer when doing so.

public void OverwriteFunctions(List<Action> brightnessServiceFunctions);

Overwrites TickFunctions with the supplied functions, briefly stopping and restarting the timer when doing so.

public void OverwriteRefreshResolution(double millisecondResolution);

Overwrites the refresh resolution to the supplied values, briefly stopping and restarting the timer when doing so.
