build function

Future<void> build({ Map? config, })

The main build function This starts the process of converting the found JSON files into Dart class definitions

Implementation

Future<void> build({Map? config}) async {
  late final Directory sourceDirectory;

    sourceDirectory = Directory(jomg['src_dir']);
    outputDirectory = Directory(jomg['output_dir']);
  } catch (_) {

  // check existence of specified directories
  if (!sourceDirectory.existsSync()) {
    throw JOMGNoSrcDirException();
  }
  if (!outputDirectory.existsSync()) {
    throw JOMGNoOutputDirException();

  // Look for JSON files and if found process and convert
  final jsonFiles = sourceDirectory.listSync(followLinks: false);
