resolve method

FmatMaterialResolution resolve(String sourcePath, { String? package, String? bundleName, })

Resolves sourcePath (the .fmat source path relative to the owning package's root, with or without the .fmat extension) to exactly one generated bundle/index entry.

Keying by source path (rather than material name) means two materials that share a name in different directories do not collide.

Implementation

FmatMaterialResolution resolve(
  String sourcePath, {
  String? package,
  String? bundleName,
}) {
  final id = _materialId(sourcePath);
  final matches = <FmatMaterialResolution>[];
  for (final index in _indexes) {
    if (package != null && index.package != package) {
      continue;
    }
    if (bundleName != null && index.bundleName != bundleName) {
      continue;
    }
    for (final entry in index.materials.values) {
      final source = entry.source;
      if (source != null && _materialId(source) == id) {
        matches.add(FmatMaterialResolution(index: index, entry: entry));
      }
    }
  }
  if (matches.isEmpty) {
    throw StateError(
      'No DataAssets-backed .fmat material for source "$sourcePath" was '
      'found. Run `dart run flutter_scene:init`, enable Dart data assets on '
      'a supported Flutter master build, and rebuild the app.',
    );
  }
  if (matches.length > 1) {
    final choices = matches
        .map((match) => '${match.index.package}/${match.index.bundleName}')
        .join(', ');
    throw StateError(
      'Multiple DataAssets-backed .fmat materials for source "$sourcePath" '
      'were found: $choices. Pass package and/or bundleName to disambiguate.',
    );
  }
