flutter_login_simple 0.0.2

Simple Flutter Firebase Authentication widget.

flutter_login_simple

A basic login for Firebase Authentication by email.

Handles the UI and Firebase Authentication in the background. It has to be initialized with:

• Image logo
• Callback function on succesful login
• Privacy HTML
• Terms of Service HTML

The callback receives user data (uid, email, ...). It also allows for calls like user.logout() and user.delete().

In case the user is aready logged in, the user the suceess-login callback function will be called.

Run the example

The example directory contains a working Flutter app. Add your Firebase config before running it: lib/firebase_options.dart.

Make sure to enable Firebase Authentication for Email in the Firebase Console. Forgetting to do so is a common pitfall.

Outlook

Add more login options and potentially theming.

Installation

flutter pub get flutter_login_simple

Please refer to the complete example.

// Your logo
Image logo = Image.network(
    'https://storage.googleapis.com/cms-storage-bucket/c823e53b3a1a7b0d36a9.png');


// Your callback will get executed on successful login.
onLoginSuccess(UserSessionData user) {
    Navigator.push(
      context,
      MaterialPageRoute(builder: (context) 
        => LoginSuccessPage(user)),
    );
}

// Your Terms of Service
String htmlToc = '<h1>Terms of Service</h1>';

// Ypur Privacy Policy
String htmlPrivacy = '<h1>Privacy Policy</h1>';

return LoginStarter(logo, onLoginSuccess, htmlToc, htmlPrivacy);

Accessing the returned UserSessionData:

user is UserSessionData;

print(user.uid);
print(user.email ?? 'not given');
print(user.displayName ?? 'not given');
// ... and so on with all properties

// void return !
await user.logoutUser();

var firebaseUser = user.firebaseUser();
