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: '[e-mail]'),
    TKeyValue(key: 'Phone', value: '[phone]'),
  ],
)

With Custom Widgets

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