What is the difference between MVC, MVP, clean architecture and MVVM Architecture Pattern? and when flutter officially support mvvm architech why you choose clean architech over mvvm ?

Architecture Patterns: MVC vs MVP vs MVVM vs Clean

Different architectural approaches:

MVC (Model-View-Controller)

textCopy
Model ←→ Controller → View
  ↑_____________________↑

Components:

• Model: Data
• View: UI
• Controller: Business logic

Pros: Simple, good for small apps Cons: View-Controller tight coupling, hard to test

MVP (Model-View-Presenter)

textCopy
Model ←→ Presenter ← View

Components:

• Model: Data
• View: UI (passive)
• Presenter: Logic (handles all events)

Pros: Better separation, testable Cons: More boilerplate

MVVM (Model-View-ViewModel)

textCopy
Model ← ViewModel → View
         (Data Binding)

Components:

• Model: Data
• ViewModel: Logic (with observable data)
• View: UI (binds to ViewModel)

Pros: Reactive, good for dynamic UIs Cons: Learning curve

Clean Architecture

textCopy
Presentation → Domain ← Data
   (UI)      (Logic)   (DB/API)

Layers:

• Presentation: UI & state management
• Domain: Business logic (entities, usecases)
• Data: Data sources, repositories

Pros: Highly testable, scalable Cons: Complex, lots of boilerplate

Comparison

Recommendation: Use Clean Architecture for production apps.
