Flutter vs Kotlin Multiplatform

 Flutter 

• Design Beautiful Apps : Concentrated more in UI 

How Flutter works ? 

• Flutter uses Widgets 
• To paint uses a library called SKI 
• It paints directly in a canvas 

Pros 

• Hot reload & hot restart 
• Material Widgets & Cupertino Widgets already made and to customise is very easy 
• Community Widgets 

Cons 

• Platform channels 
• DART : no Data class, no sealed class, no operator when, no extension function, null-safety(WIP), no functional paradigm, boilerplate, Types 

Kotlin Multiplatform Mobile 

Pros 

• Powerful language : Kotlin 
• Logic first 
• 100 % native UI 
• Legacy code support : Version migration has no problems  

Cons 

• Slow compilation : because compiling for iOS and android platforms 
• Slow development 
• Duplicating UIs 
• Developers must know iOS and Android
