TKeyValueSection class

A responsive key-value display section.

TKeyValueSection provides adaptive layout for key-value pairs with:

  • Grid layout on wide screens
  • Key-value layout on narrow screens
  • Custom breakpoint control
  • Widget support for values

Basic Usage

TKeyValueSection(
  values: [
    TKeyValue(key: 'Name', value: 'John Doe'),
    TKeyValue(key: 'Email', value: 'john@example.com'),
    TKeyValue(key: 'Phone', value: '+1234567890'),
  ],
)

With Custom Widgets

TKeyValueSection(
  values: [
    TKeyValue(key: 'Status', widget: TChip(text: 'Active')),
    TKeyValue(key: 'Actions', widget: Row(children: [...])),
  ],
)
