Flutter Movies app with Riverpod (TMDB API)

This is an improved version of my old movies app based on the latest Riverpod 2.0 APIs.

Motivation

I built this app to showcase the latest APIs for popular packages such as Riverpod and GoRouter.

This is not meant to be a complete movies app, yet it should implement common use cases and features. 👇

Current Features

• Infinite scrolling with pagination
• Pull to refresh
• Search functionality
• Loading UI with the Shimmer package
• Stateful nested routing with StatefulShellRoute

Here's a detailed tutorial explaining how the pagination and search UI works:

Planned Features (no promises 😅)

• Favourites
• Responsive UI

Packages in use

• flutter_riverpod and riverpod_generator for data caching (and much more!)
• freezed for JSON serialization
• dio for networking
• go_router for navigation
• shimmer for the loading UI
• envied for handling API keys
• cached_network_image for caching images

App Architecture & Folder structure

The project follows my Riverpod app architecture with a feature-first project structure.

More details here:

• Flutter App Architecture with Riverpod: An Introduction
• Flutter Project Structure: Feature-first or Layer-first?

It also uses the new Riverpod Generator package, which I have covered here:

• How to Auto-Generate your Providers with Flutter Riverpod Generator

Getting a TMDB API Key and Running the Project

This project uses the TMDB API to get the latest movies data.

Before running the app, you need to sign up on the TMDB website, then obtain an API key on the settings API page.

Once you have this, create an .env file at the root of the project and add your key:

// .env
TMDB_KEY=your-api-key

Then, run the code generator:

dart run build_runner build -d

This will generate a env.g.dart file inside lib/env. This contains the tmdbApiKey that is used when making requests to the TMDB API.

Congratulations, you're good to go. 😎

Note: Loading images from insecure HTTP endpoints

The data returned by the TMBD API points to image URLs using http rather than https. For the images to load correctly, the following changes have been made:

Android

Created a file at android/app/src/main/res/xml/network_security_config.xml with these contents:

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true" />
</network-security-config>

Added this to the application tag in the AndroidManifest.xml:

android:networkSecurityConfig="@xml/network_security_config"

iOS

Add the following to ios/Runner/info.pList:

  <key>NSAppTransportSecurity</key>
  <dict>
      <key>NSAllowsArbitraryLoads</key>
      <true/>
  </dict>

More information here:

• Insecure HTTP connections are disabled by default on iOS and Android.

macOS

Since macOS applications are sandboxed by default, we get a SocketException if we haven't added the required entitlements. This has been fixes by adding these lines to macos/Runner/DebugProfile.entitlements and macos/Runner/Release.entitlements:

<key>com.apple.security.network.client</key>
<true/>
