fdc library

High-performance RAD data components for Flutter data applications.

This is the primary Community entrypoint. It exposes datasets, data-aware editors, grids, filtering, sorting, searching, aggregates, export support, localization, focus management, and shared theme APIs through one stable import:

import 'package:flutter_data_components/fdc.dart';

A typical application defines an FdcDataSet, binds an FdcGrid or editor controls to it, and optionally uses an adapter when data must be loaded or applied through an external source. Lightweight entrypoints are also available for app configuration, editors, and export-only integrations.
