API reference

Every export is fully typed. The signatures and props below come from the package's own reference documentation, so what is listed here is what the installed version ships.

Components

Functions

componentSignIn

SignIn is a pre-built Flutter widget that drives the full sign-in loop using the ThunderID Flow Execution API. It renders the appropriate input form for each authentication step (username/password, TOTP, email OTP, etc.) and automatically advances through the flow until completion.

dart import 'package:thunderid_flutter/thunderid_flutter.dart'; SignIn( applicationId: '', onComplete: () { // Refresh state after sign-in ThunderIDProvider.of(context).refresh(); }, onError: (error) => print('Sign in failed: $error'), )

Example

import 'package:thunderid_flutter/thunderid_flutter.dart';

SignIn(
  applicationId: '<your-application-id>',
  onComplete: () {
    // Refresh state after sign-in
    ThunderIDProvider.of(context).refresh();
  },
  onError: (error) => print('Sign in failed: $error'),
)
