A Flutter plugin for retrieving the Android ID.
|
|
|
|
## Getting started
|
|
|
|
* Add plugin to pubspec.yaml
|
|
* Use it in your code (see examples of all methods below)
|
|
|
|
## Usage
|
|
|
|
```dart
|
|
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), <b>unique to each combination of app-signing key, user, and device.</b>
|
|
|
|
The value may change if a factory reset is performed on the device or if an APK signing key changes.
|
|
