fluct

一个帮助开发Flutter应用程序的工具

`———————————————-

安装

该工具无需添加到依赖项中,我们只需要激活即可,使用如下命令:

$ pub global activate fluct
# 或者
$ flutter pub global activate fluct

使用

fluct 目前只有两个命令creategen-assets

  • create用于创建文件及widget,文件名按Dart文件命名规则指定的单词与单词之间添加下划线,并无需指定.dart后缀,例如:index_page
  • gen-assets 用于自动生成Flutter的资源文件绑定

fluct create

Flutter开发过程中,我们创建文件是必须的,而AS自带的创建文件,并没有自动的生成相关的内容,这会让开发者非常的苦恼,类名还需要自己手动敲的话,而该命令,直接可以一步到位。

当运行此命令后,命令行会输出以下内容

Help Flutter application create a new file

Usage: fluct create [arguments] 
-h, --help            Print this usage information.
-t, --type            
          [custom]    Create a new file about custom widget in 'fluct.yaml'
                      创建自定义widget的文件,-a 为 指定你在‘fluct.yaml’文件声明的指令
          [stful]     Create a new file about StatefulWidget
                      创建StatefulWidget文件
          [stless]    Create a new file about StatelessWidget
                      创建StatelessWidget文件

-a, --arg             create a new file about your custom widget use arg in 'fluct.yaml'
                      使用你在'fluct.yaml'声明的指令

Run "fluct help" to see global options.

可以看到,该命令输出的内容是简单易懂的,我们来简单使用一下吧。

简单使用

创建IndexPage页面,继承自StatefulWidget,可以使用如下命令:

$ fluct create -t stful ./index_page
Create a new file about StatefulWidget
create class IndexPage
create success
exit 0

运行成功之后,我们会在项目下找到index_page.dart文件,内容为:

import 'package:flutter/material.dart';

class IndexPage extends StatefulWidget {
  @override
  _IndexPageState createState() => _IndexPageState();
}

class _IndexPageState extends State {
  @override
  Widget build(BuildContext context) {
    return Container();
  }
}

当然,你也可以指定哪个文件夹,例如,我要在./lib/src/page 文件夹下创建IndexPage,使用如下命令

$ fluct create -t stful ./lib/src/page/index_page

自定义内容的文件

在开始之前,我们需要在项目根目录下新建一个fluct.yaml文件,因为fluct create -t custom命令会找到它,内容如下:

inh: |
  import 'package:flutter/material.dart';

  class $NAME$ extends InheritedWidget {
    const $NAME$({
      Key key,
      @required Widget child,
    })  : assert(child != null),
          super(key: key, child: child);

    static $NAME$ of(BuildContext context) {
      return context.dependOnInheritedWidgetOfExactType(aspect: $NAME$) as $NAME$;
    }

    @override
    bool updateShouldNotify($NAME$ old) {
      return false;
    }
  }

这里,我声明了inh命令,然后运行这个命令之后会在生成文件的时候添加inh对应的内容,内容中我们值得注意的是$NAME$占位符,该字符串会被替换成根据文件名生成的内容,例如:index_page 会插入IndexPage$NAME$占位符中,最后,我们运行以下命令:

$ fluct create -t custom -a inh ./index_inherited

运行成功之后,我们能够在根目录下找到index_inherited.dart文件,内容也是对应的自定义内容

import 'package:flutter/material.dart';

class IndexInherited extends InheritedWidget {
  const IndexInherited({
    Key key,
    @required Widget child,
  })  : assert(child != null),
        super(key: key, child: child);

  static IndexInherited of(BuildContext context) {
    return context.dependOnInheritedWidgetOfExactType(aspect: IndexInherited) as IndexInherited;
  }

  @override
  bool updateShouldNotify(IndexInherited old) {
    return false;
  }
}

(NEW)fluct gen-assets

我们在使用资源文件时,需要在pubspec.yaml文件声明资源文件的路径

例如:我在./assets/images文件夹下添加a.png图片,需要在pubspec.yaml文件下声明

flutter:
  assets:
    - assets/images/a.png

或者使用文件夹路径

flutter:
  assets:
    - assets/images/

这一步如果文件多起来,很容易出现混乱,导致声明麻烦,引用麻烦,并随着项目的迭代,资源文件有些不用了,也不知道哪个是哪个,这个时候,fluct gen-assets命令帮到你

当运行fluct gen-assets -h会输出以下内容

Auto generate assets to dart file

Usage: fluct gen-assets [arguments] 
-h, --help      Print this usage information.
-a, --assets    your asset directory path -- default ./assets
                你的资源文件夹路径,默认为当前目录下的`assets`文件夹
-o, --output    your output directory path -- default ./lib/generated
                你要输出的`a.dart`文件的路径
Run "fluct help" to see global options.

到此,你已经拥有了自动资源绑定的功能了,输入fluct gen-assets即可

你可以看到,输出的内容也是非常的友好!然后我们来看以下a.dart文件

Flutter中运行命令

有小伙伴可能会疑惑,fluct create运行之后会发现未找到命令,可能你使用了flutter pub global activate fluct命令激活,这个时候,我们可以使用flutter pub run fluct create运行
