Scaffold Generator for Dart and Flutter.

scaff is a simple command-line utility for generating Dart and Flutter components from template files. It is a very tedious job to keep replicating the boilerplate codes every time you try to add a new component in your app. Using scaff, you can generate dart or flutter components from the custom-defined templates. You can even include template variables in the component files and directories name for easy and flexible scaffolding.

scaff uses 'Mustache templating library' variable schemes for defining and processing the template files.


$ pub global activate scaff


$ pub global run scaff


Let us create a simple component. First of all, we need to create a working directory and it should contain a scaff.setup.json file. The scaff.setup.json file should contain all the template variables used in the working directory. The component subdirectories and files should be included inside the working directory. The files and directories name may contain template variables as well.

Template variable examples: {{var1}}, {{className}}Base, {{fileName}}_store

The example template directory structure:

│   └── general_store_architecture
│       ├── scaff.setup.json
│       └── {{componentName}}
│           ├── {{componentName}}.dart
│           └── {{componentName}}_store.dart
  1. Create a new directory in the project root
$ mkdir -p component_templates/general_store_architecture
$ cd component_templates/general_store_architecture
  1. Create the component directory
$ mkdir {{componentName}}
$ cd {{componentName}}
  1. Create the component template file
$ touch {{componentName}}.dart
  1. Add the code to {{componentName}}.dart file
import 'package:flutter/material.dart';
import 'package:provider/provider.dart';

import '../../data/mobx/{{componentName}}_store.dart';

class {{className}}Screen extends StatelessWidget {
    Key key,
  }) : super(key: key);

  Widget build(BuildContext context) {
    final {{componentName}} = Provider.of<{{className}}Store>(context);

    return Scaffold(
      body: Center(
        child: Column(),
  1. Create the store template file
$ touch {{componentName}}_store.dart
  1. Add the code to {{componentName}}_store.dart file
import 'package:mobx/mobx.dart';

abstract class {{className}}StoreBase with Store {
  bool dummyValue = false;
  1. Create the scaff.setup.json file
$ cd ..
$ touch scaff.setup.json
  1. Add all the template variables used in the working directory to scaff.setup.json file as
  "variables": [
  "mappedVariables": {
	"componentName": "login",
	"className": "LoginScreen"
  • variables holds a list of template variables. The CLI will prompt for the user input.
  • mappedVariables holds the values for the template variables. The generator will pick values from the mappedVariables automatically, if required.
  • You may use either of the one or in combination. CLI will skip the prompt if the value for a template variable is already available inside the mappedVariables.
  1. cd into general_store_architecture folder.
$ pwd # it should be pointing to =>  /path/component_templates/general_store_architecture
  1. Run scaff globally
$ pub global run scaff
  1. You will be prompted to:
Enter source directory (/path/component_templates/general_store_architecture) »
Enter destination directory (/path/component_templates/general_store_architecture/__component__) »
Enter template extension (dart) » 
Enter 'componentName' variable value » login
Enter 'className' variable value » Login
  1. The destination directory will have the newly generated component. The destination directory structure:
└── login
    ├── login.dart
    └── login_store.dart
