Implementation

List<FigSuggestion> postProcessDockerPs(String out, [List<String>? tokens]) {
  return out

      .where((line) => line.trim().isNotEmpty)
      .map((line) {
        try {
          final parsedJSON = Map<String, String>.from((jsonDecode(line) as Map)
              .map((k, v) => MapEntry(k.toString(), v?.toString() ?? '')));
          return FigSuggestion(
            name: parsedJSON['Names'],
            displayName: '${parsedJSON['Names']} (${parsedJSON['Image']})',
            icon: 'fig://icon?type=docker',

        } catch (_) {
