How to change password using Firebase in Flutter

Question

I want to change current user password using Firebase in Flutter. Can any one help me on how to implement change password method?

As @Gunter mentioned that the feature is currently still unavailable, you can make use of the firebase REST API way of changing the password for the time being.

import 'package:http/http.dart' as http;
import 'dart:convert';
import 'dart:async';

Future changePassword(String newPassword) async {
  const String API_KEY = 'YOUR_API_KEY';
  final String changePasswordUrl =
      'https://www.googleapis.com/identitytoolkit/v3/relyingparty/setAccountInfo?key=$API_KEY';

      final String idToken = await user.getIdToken(); // where user is FirebaseUser user

    final Map payload = {
      'email': idToken,
      'password': newPassword,
      'returnSecureToken': true
    };

  await http.post(changePasswordUrl, 
    body: json.encode(payload), 
    headers: {'Content-Type': 'application/json'},  
  )
}

You can get the idToken by using the getIdToken() method on the FirebaseUser object

You can get the firebase api key under the project setting in your console
