Flutter MVVM Pattern and Provider State Management
Article Summary
Pinhome's engineering team tackled a common Flutter problem: how do you scale beyond a single page without drowning in spaghetti code?
This deep dive from Pinhome walks through implementing MVVM architecture with Provider state management in Flutter. The team refactors a basic HTTP request app into a scalable, testable architecture that separates business logic from UI code.
Key Takeaways
- BaseWidget wraps ChangeNotifier to create reusable view models for each page
- Provider dependency injection makes services available app-wide without prop drilling
- ProxyProvider3 handles complex service dependencies with clean constructor injection
- Router system manages navigation with type-safe route constants
- ViewModel stores page state and API calls, keeping UI code purely presentational
Critical Insight
MVVM with Provider transforms Flutter apps from single-page demos into maintainable, testable codebases ready for production scale.
