loadConfigFileFromArgResults function

Map<String, dynamic> loadConfigFileFromArgResults(ArgResults argResults, { bool? verbose, String? cwd, })

Call loadConfigFile with arguments inferred from argResults.

If an error occurs and the (optional) verbose is true, log a description to stderr.

Treat the current working directory as cwd (if given), else, use './' as the current working directory.

Note: cwd was added to allow tests that require different working directories to run at the same time, without conflicting.

Implementation

Map<String, dynamic> loadConfigFileFromArgResults(ArgResults argResults,
    {bool? verbose, String? cwd}) {
  verbose ??= false;
  cwd ??= './';

  String? configFile = argResults[fileOption];
  final String? fileOptionResult = argResults[fileOption];

  if (configFile != null) {
    configFile = path.join(cwd, configFile);
  }

  // if icon is given, try to load icon
  if (configFile != null && configFile != defaultConfigFile) {
    try {
      return loadConfigFile(configFile, fileOptionResult);
    } catch (e) {
      if (verbose) {
        stderr.writeln(e);
      }
      return <String, dynamic>{};
    }
  }

  // If none set try flutter_launcher_icons.yaml first then pubspec.yaml
  // for compatibility
  try {
    return loadConfigFile(path.join(cwd, defaultConfigFile), fileOptionResult);
  } catch (e) {
    // Try pubspec.yaml for compatibility
    if (configFile == null) {
      try {
        return loadConfigFile(path.join(cwd, 'pubspec.yaml'), fileOptionResult);
      } catch (_) {}
    }

    // if nothing got returned, print error
    if (verbose) {
      stderr.writeln(e);
    }
  }

  return <String, dynamic>{};
}
