build method

@override Future<void> build(BuildStep buildStep)

Generates the outputs for a given BuildStep.

Implementation

@override
Future<void> build(BuildStep buildStep) async {
  print("generate proto ${buildStep.inputId.path}");
  if (protoDir == null || (!dartEnable && !javaEnable && !ocEnable)) {
    return;
  }

  // Read the input path to signal to the build graph that if the file changes
  // then it should be rebuilt.
  await buildStep.readAsString(buildStep.inputId);

  await downloadDepsFuture;
  await Future.wait([
    _genDartCode(buildStep),
    _genJavaCode(buildStep),
    _genOcCode(buildStep)
  ]);
