flutter_compass

• Flutter Compass no more depends on RxDart

• Migrate to null safety

Android:

• Remove roll from heading calculations
• Uses matrix reorientation to do a better job calculating heading "out the back of the phone" iOS:
• Use the device motion orientation matrix to compute heading out the back of the device. This is much like what is done on Android, and yields a more stable and precise heading. Dart:
• Add documentation to flutter_compass.dart.

Breaking Change: The events stream now gives you CompassEvent that consists of heading, headingForCamera and accuracy.

Android: Remove roll from heading calculations

Use geomagnetic rotation sensor as fallback on Android

Minor fix

Updated rxDart to 0.24.0

Updated README.md

Breaking change: Uses magnetic heading by default for iOS.

Older versions used True heading and which caused deviations.

• Sensor check added on android. null is returned as direction when no sensor available.

• Upgrade rxdart version to 0.23.1

• Improve README.md

• Add dispose method

• Update permission_handler to 3.2.2
• Update rxdart to 0.22.3

• Android: The plugin will now remember the last read azimuth. This will be done across Isolates using a static variable. Additionally, the value is cached within the isolate with the introduction of a RxDart BehaviorSubject. Reading the current azimuth using await FlutterCompass.events.first will therefore not hang anymore when th user has not moved the handset at all.
• Sample updated to cover the functional updates in Android.
• Added missing locatio permissions to the Android example which prevented the permission dialog from being shown.

• Upgrade Android build components (Kotlin version) Breaking change. Migrate from the deprecated original Android Support Library to AndroidX. This shouldn't result in any functional changes, but it requires any Android apps using this plugin to also migrate if they're using the original support library.
• Upgrade iOS component to Swift 4.2

• Added example
• Added public api docs

• bug fixes

• Android emulator fix

• flutter compass plugin
