flutter_map_sld_io #

File and HTTP loading for OGC SLD/SE styles. Adapter package for flutter_map_sld.

Dart VM and server environments only (dart:io dependency).

Features #

• Load SLD from local file path (SldIo.parseFile)
• Load SLD from HTTP/HTTPS URL (SldIo.parseUrl)
• Typed error handling via sealed SldLoadResult union
• Transport errors separated from XML parse issues

Usage #

import 'package:flutter_map_sld_io/flutter_map_sld_io.dart';

// From file
final fileResult = await SldIo.parseFile('/path/to/style.sld');

// From URL
final urlResult = await SldIo.parseUrl(
  Uri.parse('https://example.com/style.sld'),
);

// Pattern matching
switch (urlResult) {
  case SldLoadSuccess(:final parseResult):
    final doc = parseResult.document;
    // use doc...
  case SldLoadFailure(:final error):
    print('${error.kind}: ${error.message}');
}
