createFeature function

void createFeature(CreateOptions opts, ProjectContext ctx)

river_cli create feature:<name> --fields "..." (or --json)

The "amazing" generator: model + repository + AsyncNotifier controller + list view + registered route, all wired together and adapted to the installed modules.

Implementation

void createFeature(CreateOptions opts, ProjectContext ctx) {
  final snake = Naming.snake(opts.name);
  final featureDir = '${opts.path}/$snake';
  final writer = FileWriter(force: opts.force, dryRun: opts.dryRun);

  print('Creating feature: ${Naming.pascal(opts.name)} at $featureDir\n');

  // Shared data layer (model may be inferred from JSON).
  final inferred = _inferredModels(opts);
  final modelContent = inferred != null
      ? modelsFileTemplate(inferred)
      : modelTemplate(opts.name, opts.fields);
  if (inferred != null) {
    print('  inferred ${inferred.length} model(s) from JSON');
  }
