# shared_preferences_platform_interface

A common platform interface for the [`shared_preferences`][1] plugin.

This interface allows platform-specific implementations of the `shared_preferences`
plugin, as well as the plugin itself, to ensure they are supporting the
same interface.

# Usage

To implement a new platform-specific implementation of `shared_preferences`, extend
[`SharedPreferencesPlatform`][2] and [`SharedPreferencesAsyncPlatform`][3] with
implementations that perform the platform-specific behaviors, and when you register
your plugin, set the default `SharedPreferencesStorePlatform` and
`SharedPreferencesAsyncPlatform` by calling the `SharedPreferencesPlatform.instance`
and `SharedPreferencesAsyncPlatform.instance` setters.

Please note that the plugin tooling only registers the native and/or Dart classes
listed in your package's `pubspec.yaml`, so if you intend to implement more than
one class, you will need to manually register the second class
(as can be seen in the Android and iOS implementations).

# Note on breaking changes

Strongly prefer non-breaking changes (such as adding a method to the interface)
over breaking changes for this package.

See https://flutter.dev/go/platform-interface-breaking-changes for a discussion
on why a less-clean interface is preferable to a breaking change.
