Usage

const _androidIdPlugin = AndroidId();

final String? androidId = await _androidIdPlugin.getId();

Important

Please note that on Android 8 and above, the Android ID is not unique per device, but also per signing key the app was built with:

<blockquote> On Android 8.0 (API level 26) and higher versions of the platform, a 64-bit number (expressed as a hexadecimal string), unique to each combination of app-signing key, user, and device.

The value may change if a factory reset is performed on the device or if an APK signing key changes.
