A flutter OAuth package for Slack with Firebase Authentication integration

flutter_slack_oauth_firebase

Extension for our flutter_slack_oauth library which adds support for Firebase Authentication and Cloud Firestore.

Usage
- To use this plugin, add flutter_slack_oauth_firebase as a dependency in your pubspec.yaml file.
This package depends on Firebase Auth, so be sure to follow those steps. Unlike the documentation for that package, the Google Sign-in plugin for Firebase Auth is NOTrequired!
Deploy the Firebase Functions project in the firebase folder, which is the "backend" logic that will handle the OAuth flow. You can follow the steps as specified in the Instagram Oauth Firebase Functions sample.

After succesful login

The resulting access token for Slack is stored in Firebase Firestore in the slackAccessToken collection under a document with the Slack UID as document id.
User info returned from the Slack login is stored in Firebase Firestore in the userscollection under a document with the Slack UID as document id.
You can easily find the Slack UID for the current user after login:

FirebaseUser user = await _auth.currentUser();
print(user.uid);

Full Example

import 'package:firebase_auth/firebase_auth.dart';
import 'package:flutter/material.dart';
import 'package:flutter_slack_oauth_firebase/flutter_slack_oauth_firebase.dart';

void main() {
  final FirebaseAuth _auth = FirebaseAuth.instance;

  runApp(new MaterialApp(
    home: new Scaffold(
      appBar: new AppBar(
        title: new Text("Slack OAuth Example"),
      ),
      body: new Builder(
        builder: (BuildContext context) {
          return new Center(
            child: new FirebaseSlackButton(
              clientId: "XXX_CLIENT_ID_XXX",
              clientSecret: "XXX_CLIENT_SECRET_XXX",
              redirectUrl:
              "https://XXX-FIREBASE-PROJECT-XXX.firebaseapp.com/completed.html",
              firebaseUrl:
              "https://XXX-FIREBASE-PROJECT-XXX.firebaseapp.com/index.html",
              onSuccess: () async {
                // get Firebase User:
                FirebaseUser user = await _auth.currentUser();

                Scaffold.of(context).showSnackBar(new SnackBar(
                  content: new Text('Logged in with Slack ID ' + user.uid),
                ));
              },
              onFailure: () {
                Scaffold.of(context).showSnackBar(new SnackBar(
                      content: new Text('Slack Login Failed'),
                    ));
              },
              onCancelledByUser: () {
                Scaffold.of(context).showSnackBar(new SnackBar(
                      content: new Text('Slack Login Cancelled by user'),
                    ));
              },
            ),
          );
        },
      ),
    ),

How to use the Widget pass-in method - recommended for better experience

DateTime selectedDate = DateTime.now();
DateTime startDate = DateTime.now().subtract(Duration(days: 10));
DateTime endDate = DateTime.now().add(Duration(days: 10));
Map<String, Widget> widgets = Map();
String widgetKeyFormat = "yyyy-MM-dd";

body: ScrollingDayCalendar(
          startDate: startDate,
          endDate: endDate,
          selectedDate: selectedDate,
          dateStyle: TextStyle(
            fontWeight: FontWeight.bold,
            color: Colors.white,
          ),
          displayDateFormat: "dd, MMM yyyy",
          dateBackgroundColor: Colors.grey,
          forwardIcon: Icons.arrow_forward,
          backwardIcon: Icons.arrow_back,
          pageChangeDuration: Duration(
            milliseconds: 700,
          ),
          widgets: widgets,
          widgetKeyFormat: widgetKeyFormat,
          noItemsWidget: Center(
            child: Text("No items have been added for this date"), // add buttons etc here to add new items for date
          ),
        ),

How to use the SetState method

// set the initial page value
Widget _pageItems = Text("Inital value");
DateTime selectedDate = DateTime.now();
DateTime startDate = DateTime.now().subtract(Duration(days: 10));
DateTime endDate = DateTime.now().add(Duration(days: 10));
String widgetKeyFormat = "yyyy-MM-dd";

// add to body of a Scaffold
body: ScrollingDayCalendar(
          startDate: startDate,
          endDate: endDate,
          selectedDate: selectedDate,
          onDateChange: (direction, DateTime selectedDate) {
            setState(() {
              pageItems = _widgetBuilder(selectedDate);
            });
          },
          dateStyle: TextStyle(
            fontWeight: FontWeight.bold,
            color: Colors.white,
          ),
          pageItems: pageItems,
          displayDateFormat: "dd/MM/yyyy",
          dateBackgroundColor: Colors.grey,
          forwardIcon: Icons.arrow_forward,
          backwardIcon: Icons.arrow_back,
          pageChangeDuration: Duration(
            milliseconds: 400,
          ),
          noItemsWidget: Center(
            child: Text("No items have been added for this date"), // add buttons etc here to add new items for date
          ),
        ),
