Requirements Breakdown & Implications

1. It must be loaded as dependency.
   • Should be published as an independent package (currently as independent github repo).
   • Applications import it as a library, not copy/paste code.
   • Suggests versioned releases and semantic versioning.
2. Can adapt cross-application theming.
   • Needs a global theming system.
   • Themes should be pluggable per application.
3. Minimal Integration efforts.

   • Components should have sensible defaults.

   • Integration should be just:

     KMultiSelectDropDown<LookUp>(
     	name: SInfoQuestion.fContri.name,
     	label: SInfoQuestion.fContri.question,
     	items: state.meta.lookUps,
     ),

   • Avoid heavy configuration.

4. Compile-time errors for missing implementations.

   • Strongly typed with Generics/Interfaces.

   • If a component requires a handler or prop, the compiler should fail.

   • Example:

     mixin KSelectable<T> implements Equatable {
       T get value;
      
       String get displayName;
     }
      
     class Country with KSelectable<Country> { //<----- Must give compile time error. Developer must override respective fields.
       final int id;
       final String name;
      
       const Country({this.id = 0, this.name = ''});
     }

5. Layout must be configurable & overridable without rewriting component internal logic.

   • Use composition over inheritance.

   • Expose builders for layout overrides.

   • Example:

     HTMeta<String, Entity, EntityParentService>(
     	builder: (_, value, __) {
     		return Padding(
     					padding: EdgeInsets.only(left: 30),
     					child: Text(value ?? ''),
                 	);
               },
     )
      

6. Partial use also should be allowed whenever required.
   • Consumers can import only required components.
   • For more clarification, check interdependent components.
7. State management & data management must be implicit.
   • Components should handle local state internally (e.g., load data, show shimmers, modal open/close, dropdown toggle).
   • Allow optional controlled state for advanced use.
8. Must be scalable for future expansions.
   • Should follow SOLID principles.
   • Should follow DRY principle.
