DataSourceRegistry class

Registry for managing data source implementations.

This singleton class maintains a registry of all available data sources and provides methods to register new sources and find appropriate handlers for URIs.

Example

// Register a custom source
DataSourceRegistry.register(S3DataSource());

// Find handler for a URI
final source = DataSourceRegistry.findByUri(Uri.parse('s3://bucket/data.csv'));
if (source != null) {
  final df = await source.read(uri, {});
}
