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
😅 )
Planned Features (no promises - Favourites
- Stateful nested routing
- 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 Project Structure: Feature-first or Layer-first?
It also uses the new Riverpod Generator package, which I have covered here:
Getting a TMDB API key
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:
flutter pub run build_runner build --delete-conflicting-outputs
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. In order for 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>

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/>
