Notes / Description

This pull request introduces a new "Simple Date Input" component to the Carbon date picker suite, providing a text-based date entry field with validation and formatting support. The implementation includes the main composable, its state management, and comprehensive tests. Additionally, the new component is integrated into the catalog demo screen for demonstration purposes.

New Simple Date Input Component:

• Added the SimpleDateInput composable, which allows users to type dates directly into a text field, with support for placeholder, helper text, and input state (enabled, error, disabled, read-only). This component delegates parsing and formatting to a state object and provides accessibility semantics.
• Introduced SimpleDateInputState and its implementation, handling date parsing, formatting, validation callbacks, and state restoration via Compose's Saver. Includes a rememberSimpleDateInputState function for lifecycle-aware state management.

Testing:

• Created SimpleDateInputTest with extensive unit tests for layout, semantics, validation, state restoration, and programmatic updates, ensuring robustness and correct behavior of the new component.

Catalog Integration:

• Updated imports in DatePickerDemoScreen.kt to include SimpleDateInput and its state, preparing the catalog for a demo of the new component.

Platforms testing checklist

• Android
• iOS
• Desktop
  • Linux
  • Apple
  • Windows
• WASM
