android_auto_platform_interface 0.1.2

Common platform interface for the android_auto plugin. Defines the contract every platform implementation has to fulfil.

android_auto_platform_interface

The contract between android_auto and its platform implementations. Pure Dart, no native code, no aasdk derived code.

Most people want android_auto instead. This package is for writing a new platform implementation, or for a host app that needs a type the app facing package does not re-export.

What is in it

• AndroidAutoPlatform, the interface every implementation extends.
• AndroidAutoConfig: the projected size, frame rate and density, how the head unit describes itself to the phone, and which sensors, metadata channels and transports it offers.
• The models everything else is expressed in: connection state and events, video information, touch and key input, audio streams and devices, the twelve sensors, the five metadata kinds with their navigation, media, telephony, notification and browse payloads, and the wireless configuration and status.

Writing an implementation

Extend AndroidAutoPlatform and set AndroidAutoPlatform.instance. The base class uses plugin_platform_interface, so implementations must extend it rather than implement it, which is what lets methods be added later without breaking every implementation at once.

Some enums cross a foreign function boundary positionally in the Linux implementation, so their declared order is part of the platform boundary rather than an internal detail. Those say so in their own doc comments.
