{

			<string>com.googleusercontent.apps.------------------------</string>
		</array>
	</dict>
</array>
<!-- End of the Google Sign-in Section -->

Phone number sign-in #

Phone Sign In UI

  • In most cases, you want to use Firebase Flutter UI for Firebase Sign-In and that's very fine. But with the Phone Sign-In built in UI, it's not easy to handle errors. So, fireflutter provides simple service for phone sign in.

  • To use phone sign-in, enable it. (and add some test phone numbers if you wish to test with test phone numbers.)

  • PhoneService has the service code of phone sign-in.

  • Fireflutter also provides UI widgets to make it easy to use in your app.

    • Simply add PhoneNumberInput widget to your screen and on code sent, move to sms code input page and add SmsCodeInput widget.
    • See example/lib/phone_sign_in_ui foler for sample code.

User presence #

User presence overview #

User Presence

  • More often, people want to know if their friends are online or not. Use this feature to know who is online. It has three status; 'online', 'offline', and 'away'.

User Presence Installation #

class _MainAppState extends State<MainApp> {
  @override
  void initState() {
    super.initState();
    Presence.instance.activate();
  }

  @override
  void dispose() {
    super.dispose();
    Presence.instance.activate(
      onError: (e) => print('--> Presence error: $e'),
    );
  }
}
  • To know if a user is online, offline or away, use UserPresence widget.
UserPresence(
  uid: uid,
  onlineBuilder: () => Row(
    children: const [
      Icon(Icons.circle, color: Colors.green),
      Text('Online'),
    ],
  ),
  offlineBuilder: () => Row(
    children: const [
      Icon(Icons.circle, color: Colors.red),
      Text('Offline'),
    ],
  ),
  awayBuilder: () => Row(
    children: const [
      Icon(Icons.circle, color: Colors.yellow),
      Text('Away'),
    ],
  ),
),

User Presence Logic #

  • Run Presence.instance.activate() at start if you want to track the presence status of users.
  • If user didn't login to the device, the user will be offline by default.
  • If Presence is working, you will see the record in firebase realtime database data section in firebase console.
    • If no documents appears in firebase realtime database data section, then see the installation and issues.
  • /presense/$uid document will be written only when user logs in and out.
  • When app is closed, the user will be offline.

TODOs #

Find Friends #

  • Idea: See if you are looking for a friend in a busy city. When you and your friend are connected, you can find each other by sharing geo location.
  • Implementaion: put find button and when connected, display position in map and update the geo location.
