Fast CLI #




An incredible command line interface for Flutter. It allows you to create your own CLI without coding a line.
With this CLI, you can create your custom templates and define how your project will start.
The generated directories and files are defined from the outside in, that is, the users define the resources, the CLI generates for you.
You can easily:

Create
Use
Edit
Share

Do not hesitate to share the plugins created by you with the community, it is very simple.

Overview #

Plugin System - Provide the mechanism for you to import a set of templates, resources and custom commands.
Custom Commands - Commands defined by you to be executed in cmd.
Scaffold - An initial structural for a project(Start your project with a structure already defined)
Template - (Code that will be created for your project, as if it were a snippet, but by command line)

Quick Start #
Quick use of CLI features.
Install your first plugin #
The plugin system is the way in which you can create, use and share your own resources. Think of them as plugins for VS Code, but in this case for a CLI.
To use the CLI it is necessary to install at least one plugin, so install your first plugin with the command below.
Don't worry, just below you will learn how to create your own plugin. For now just install this plugin already created.
fast plugin add <repository that has a plugin>
copied to clipboard
Example:
$ fast plugin add git https://github.com/pbissonho/mvc_git_test.git
copied to clipboard
See what the plugin provides #
After installing the plugin, an executable is created with his name, so run the command below to test.
Use the "mvc" plugin that was installed directly from the repository.
This command will display the functionalities that the plugin provides.
$ mvc --help

Use a plugin scaffold #
<plugin_name> create --name <flutter_projet_name> --scaffold <_scaffold_name>
copied to clipboard
Create a flutter application called "myapp" with the structure defined in the "sample" scaffold of the "mvc" plugin
Example:
$ mvc create --name myapp --scaffold sample
copied to clipboard
Run a plugin custom command #
mvc run <custom_command_name>
copied to clipboard
Example:
$ mvc run build
copied to clipboard
Use a plugin template #
mvc <template_name> <template_arg1> <template_arg2> <template_arg3>...
copied to clipboard
$ mvc page --name myPage
copied to clipboard
Plugin System #
The plugin system is the way in which you can create, use and share your own resources. Think of them as plugins for Visual Studio Code, but in this case for a CLI.
This CLI is intended to provide the tool for you to create your own CLI, by default the CLI comes with no resources, that is, it does not have any available plugin, command or scaffold. So to use it is necessary to install at least one plugin.
In Visual Studio Code the plugins can provide snippets, themes, icons and other things.
In this CLI the plugins provide:

Commands
Scaffolds
Templates

Structure of a plugin:
scaffolds/ <- Folder to add the scaffols.
templates/ <- Folder to add the templates.
commands.yaml <- File to define custom commands
plugin.yaml <- File to define the name and description of the plugin.
See an example on github clicking here..
Using a plugin #
First instal the plugin. You can install directly from a repository.
When adding a plugin an executable is created with the name of the plugin, so after installing it it is possible to use it by the plugin's own name.
Install:
$ fast plugin add git https://github.com/pbissonho/mvc_git_test.git
copied to clipboard
Use:
$ mvc --help
copied to clipboard
Plugin Commands #
add
Add a plugin
It is possible to add a plugin directly from a github repository or some local path.
Install directly from a repository.
$ fast plugin add git https://github.com/pbissonho/mvc_git_test.git
copied to clipboard
Install from a local path.
$ fast plugin add path home/mypath/
copied to clipboard
remove
Removes a plugin.
$ fast plugin remove --name <plugin_name>
copied to clipboard
list
Show all installed plugins.
$ fast plugin list

Scaffold #
A scaffold is a yaml file where you can define a folder structure and a set of dependencies for a Flutter project.
Instead of creating a blank Flutter project, you can start the project with a folder structure already created and the dependencies configured.
Also you can add custom files with copy_files: true option and adding files folder inside your scaffold folder. You can use @appName or @AppName tag to replace it with your app name, for example to define imports.
Define a scaffold.yaml #
To define your scaffold just follow the example below:
file: scaffold.yaml
# The scaffold name.
name: sample
description: A sample scaffold.
author: Pedro Bissonho <[email protected]>

# The folder structure that will be generated inside the 'lib' folder.
structure:
- ui:
- pages
- shared
- themes
- data:
- models
- repositorys
- blocs
# The folder structure that will be generated inside the 'test' folder.
test_structure:
- ui:
- data:
- fixtures:

# The standard dependencies that the project will have.
# Your project will start with all these dependencies.
# If the version is not informed, the version will be configured as the last version available in Dart Pub.
dependencies:
koin:
flutter_bloc:

# The standard dev_dependencies that the project will have.
# If the version is not informed, the version will be configured as the last version available in Dart Pub.
dev_dependencies:
koin_test:

Use a scaffold #
Add your scaffold.yaml file inside a plugin and then use it.
<plugin_name> create --name <app_name> --scaffold <scaffold_name>
copied to clipboard
Example:
$ mvc create --name myapp --scaffold mvc1
copied to clipboard
Result #
When starting your project with the sample scaffold you will have that project as a result.

Example with copy_files option enabled #
file: scaffold.yaml
# The scaffold name.
name: clean

author: Alberto Chamorro <[email protected]>

# Copy files option enabled
copy_files: true

# The folder structure that will be generated inside the 'lib' folder.
structure:
- ui:

Then create a folder with name "files" and put your content there.

All tags '@AppName' and '@appName' would be replaced with your application name.
Add your scaffold.yaml file inside a plugin and then use it.
<plugin_name> create --name <app_name> --scaffold <scaffold_name>

Example:
$ fast_files_sample create --name myapp --scaffold clean

You have a repository with this example here
Template #
Templates are files or a set of files that you use to generate code. Generate code as snippets, but by command line.
Define a template #
First we define the files that are generated.
In this example, the '@Name' tag will be replaced by the '--name' argument when the file is generated.
file: @name_page.dart
import 'package:flutter/material.dart';

class @NamePage extends StatefulWidget {
@override
_@NamePageState createState() => _@NamePageState();
}

class _@NamePageState extends State<@NamePage> {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Container(
child: Text("Hello"),
),
);
}
}
copied to clipboard
In the same folder as the file above we have the yaml file that defines how the template should be created.
file: template.yaml
#Yaml file for configuring the template.
#The template name
name: page
#The template description
description: Create_flutter_page.
#Path where files should be sent
to: lib/ui/pages/@name
#Arguments to be passed when executing this template
# You can define as many arguments as you want.
args:
- name
# - other1
# - other2
# - other3
copied to clipboard
Using a template #
Run this command so that your template is generated.
<plugin_name> <template_name> <templates_arg1, templates_arg2, templates_arg3...>
copied to clipboard
example:
$ mvc page --name home
copied to clipboard
Result #
You will now have the following file in the path lib/ui/pages/home
import 'package:flutter/material.dart';

class HomePage extends StatefulWidget {
@override
_HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Container(
child: Text("Hello"),
),
);
}
}

Snippets generator #
A command to generate snippets for the VC Code based on the template files.
Reuse the code inserted in the template files to generate snippets for Visual Studio Code.
Define your snippets #
First we create the template file and template.yaml.
And then set a snippe to be generated.
file: @name_page.dart
import 'package:flutter/material.dart';

class @NamePage extends StatefulWidget {
@override
_@NamePageState createState() => _@NamePageState();
}

class _@NamePageState extends State<@NamePage> {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Container(
child: Text("Hello"),
),
);
}
}
copied to clipboard
file: template.yaml

name: page
description: Create_flutter_page.
to: lib/ui/pages/@name
# You can define as many arguments as you want.
args:
- name

# Set up a list of snippests.
snippets:
# The file containing the snippet code to be generated
# Reuse the code inserted in one of the template files to generate a VC Code snippets.
- file: '@name_page.dart'
prefix: page
#File lines that will not be included in the snippet.
excluded:
- 0
- 1
# It is possible to create snippests for each template file.
# - file: '@name_other1.dart'
# prefix: other1
# excluded:
# - 0
# - file: '@name_other2.dart'
# prefix: other2
# excluded:
# - 0

copied to clipboard
Generate snippests #
Snippests are generated only for the called plugin, so
if I had more snippes installed they will not be generated for them.
Run the command below to generate the snippets.
<plugin_name> snippets
copied to clipboard
Example:
$ mvc snippets
copied to clipboard
Result #
It will be possible to use the generated snippet.

Custom Commands #
Recording and having to write commands like 'flutter pub run build_runner build --delete-conflicting-outputs' it's not a cool thing to do.
,so the custom commands will solve this problem. Write only once and then use them for an alias.
You only need to create a commands.yaml file in your plugin and define your commands.
Define your commands #
file: commands.yaml
commands:
build: flutter pub run build_runner build
buildx: flutter pub run build_runner build --delete-conflicting-outputs
watch: flutter pub run build_runner watch
push: git push origin master

Running a command #
<plugin_name> run <command_name>
copied to clipboard
example:
$ mvc run build
copied to clipboard
Migrating #
v0.3 to v0.4 #
The commands "config template",'config scaffolds' and 'config commands' have been removed. It is now much easier to configure the CLi and start using it. Just create your plugin and install it.
The scaffolds, templates and commands remain exactly the same, so you will use version 0.4 without making any changes, just add them to your plugin.
