Runs this command.

The return value is wrapped in a Future if necessary and returned by CommandRunner.runCommand.

Implementation

@override
Future<void> run() async {
  di<ValueMapper>().init(
    bytesPrefix: getArgBytesPrefix(argResults),
    locationPrefix: getArgLocationPrefix(argResults),
    referencePrefix: getArgReferencePrefix(argResults),
    datetimePrefix: getArgDateTimePrefix(argResults),
  );

  di<DocumentMapper>().init(metaPrefix: getArgMetaPrefix(argResults));

  final firestore = await initFirestore(
    project: getArgProject(argResults),
    database: getArgDatabase(argResults),
    usage: usage,
  );

  final restArgs = argResults!.rest;

  checkHaveOnlyOneArg(
    restArgs: restArgs,
    usage: usage,
  );

  final relPath = restArgs.single;

  final docJson = await firestore.getDocument(documentPath: relPath);

  final jsonOut = jsonEncoder.convert(docJson);
  await writeToOut(
    jsonOut,
    fileName: getArgOut(argResults),
  );
