Flutter with Firebase Course

Lesson 1 • Flutter Project Structure Overview

Examine the anatomy of a Flutter project: folders, entry points, and pubspec.yaml. Understanding this structure prevents configuration errors throughout the course.

Lesson 2 • Introduction to Firebase Services

Survey Firebase products—Auth, Firestore, Storage, and Hosting—and their roles. This overview frames which service solves which problem in later chapters.

Lesson 3 • Dart Language Essentials for Flutter

Cover Dart syntax, null safety, and async patterns required to write Flutter apps. These language fundamentals underpin every widget and Firebase call ahead.

Lesson 4 • Connecting Flutter to Firebase

Add Firebase to a Flutter project using FlutterFire CLI and platform config files. A verified connection here is the prerequisite for all Firebase feature chapters.

Lesson 1 • Forms and User Input

Build validated forms using TextFormField, Form widget, and GlobalKey. Form handling is directly reused in the Firebase Authentication chapter.

Lesson 2 • Stateless and Stateful Widgets

Distinguish when to use StatelessWidget vs. StatefulWidget and manage local state with setState. This choice drives UI reactivity in every screen built later.

Lesson 3 • Navigation and Routing

Implement named routes and Navigator 2.0 for multi-screen apps. Proper navigation architecture supports auth flows and deep linking introduced in later chapters.

Lesson 4 • Core Layout Widgets

Use Column, Row, Stack, Container, and Expanded to compose screens. Mastering layout widgets is essential before building Firebase-driven list and form UIs.

Lesson 1 • Auth-Driven Navigation and Guards

Redirect users based on auth state using StreamBuilder and route guards. Protecting screens from unauthenticated access is a critical production requirement.

Lesson 2 • Firebase Auth Core Concepts

Understand the FirebaseAuth instance, User object, and auth state stream. These concepts are the backbone of every sign-in method covered in this chapter.

Lesson 3 • Email and Password Authentication

Build sign-up, sign-in, and password-reset screens using Firebase email/password auth. This is the most common auth method and the template for other providers.

Lesson 4 • Google and Social Sign-In

Integrate Google Sign-In using the google_sign_in package and Firebase credential linking. Social auth reduces friction and is required for many production apps.

Lesson 1 • Querying and Filtering Data

Filter, sort, and paginate Firestore data using where(), orderBy(), and startAfterDocument(). Efficient queries reduce reads and lower Firebase costs.

Lesson 2 • CRUD Operations in Flutter

Add, read, update, and delete documents using the cloud_firestore package. These operations are the building blocks of every data-driven feature.

Lesson 3 • Firestore Data Model Fundamentals

Understand collections, documents, subcollections, and data types in Firestore. A correct mental model prevents costly schema redesigns later in the project.

Lesson 4 • Data Modeling Best Practices

Apply denormalization, fan-out writes, and aggregation patterns to Firestore schemas. These patterns ensure performance at scale and minimize read costs.

Lesson 1 • Storage Security Rules

Write Storage security rules to restrict file access by user identity and path. Proper rules prevent data breaches and are required before production deployment.

Lesson 2 • Downloading and Displaying Files

Retrieve download URLs and display images using cached_network_image. Efficient display patterns prevent redundant network calls and improve UX.

Lesson 3 • Firebase Storage Architecture

Understand Storage buckets, reference paths, and security rules for files. This foundation prevents unauthorized access and misorganized file hierarchies.

Lesson 1 • Testing State Management Logic

Write unit tests for StateNotifiers and mock Firebase dependencies with ProviderContainer. Testable state logic reduces bugs and speeds up feature development.

Lesson 2 • Riverpod Core Concepts

Define providers, StateNotifiers, and AsyncNotifiers using Riverpod 2.x syntax. Riverpod's compile-time safety and testability make it the preferred choice for production.

Lesson 3 • State Management Fundamentals

Contrast setState, InheritedWidget, and third-party solutions to understand when each applies. This context justifies the architectural choices made throughout the chapter.

Lesson 4 • Integrating Firebase Streams with Riverpod

Expose Firestore and Auth streams as StreamProviders consumed by Flutter widgets. This pattern decouples UI from Firebase and enables clean architecture.

Lesson 1 • Authentication-Based Access Control

Restrict document access using request.auth and user UID comparisons. These patterns implement per-user data isolation in multi-tenant apps.

Lesson 2 • Security Rules Fundamentals

Learn rules syntax, match statements, and allow conditions for Firestore. Understanding the rules engine is mandatory before writing any production rule.

Lesson 3 • Data Validation in Rules

Validate incoming data types, required fields, and value ranges inside rules. Server-side validation prevents malformed data even when client code is bypassed.

Lesson 1 • Push Notifications with FCM

Send targeted and topic-based push notifications using Firebase Cloud Messaging. Notifications drive re-engagement and are required in most consumer apps.

Lesson 2 • Building and Deploying the App

Configure release builds, signing, and CI/CD pipelines for Android and iOS. A repeatable deployment process is the final step before reaching real users.

Lesson 3 • Remote Config and A/B Testing

Serve dynamic app configuration and run experiments using Firebase Remote Config. Feature flags and A/B tests enable safe rollouts without app store updates.

Lesson 4 • Firebase Analytics and Crashlytics

Log custom events with Firebase Analytics and capture crashes with Crashlytics. Observability data drives product decisions and reduces mean time to resolution.
