A Flutter package used to update widget tree dynamically

Last update: Dec 30, 2022

Overview

Fair is a lightweight package for Flutter, which can be used to update widget tree and state dynamically. This package is still at an early stage.

We create Fair so we can dispatch any pages changes to users as bundle(s), the way similar to React Native. With Flutter Fair integrated, you can publish your pages without waiting for the next release date of your App. Fair provides standard widget and some logic plugins, it can be used as a new dynamic page or as part of existing Flutter page.

Quick Start

Use Flutter Fair require few steps.

step1：download fair project source code

It is recommended to download fair to the local and dependencies on the relative path.

The download method is as follows:

git clone https://github.com/wuba/fair.git

step2：Add dependency inside pubspec.yaml

Assuming that the fair project and your own project are in the same folder:

# add Fair dependency
dependencies:
  fair:
    path: ../fair/fair

# add compiler dependency
dev_dependencies:
  build_runner: ^1.4.0
  fair_compiler:
    path: ../fair/compiler
 
# switch "fair_version" according to the local Flutter SDK version
dependency_overrides:
  fair_version:
    path: ../fair/flutter_version/flutter_2_0_6

step3：Wrap your app with FairApp Widget

void main() {
  WidgetsFlutterBinding.ensureInitialized();

  FairApp.runApplication(
    _getApp(),
    plugins: {
    },
  );
}

dynamic _getApp() => FairApp(
  modules: {
  },
  delegate: {
  },
  child: MaterialApp(
    home: FairWidget(
            name: 'DynamicWidget',
            path: 'assets/bundle/lib_src_page_dynamic_widget.fair.json',
            data: {"fairProps": json.encode({})}),
  ),
);

step4：Import a dynamic widget as FairWidget

FairWidget(
  name: 'DynamicWidget',
  path: 'assets/bundle/lib_src_page_dynamic_widget.fair.json',
  data: {"fairProps": json.encode({})}),

- assets/images/ 无效的资源路径

错误信息： Error: unable to find directory entry in pubspec.yaml: /Users/cinson/.pub-cache/hosted/pub.flutter-io.cn/fair-3.0.0/assets/images/

查看fair_release_3.0分支和v3.0.0的tag，发现代码有差异，tag中多引了- assets/images/ ，但是asset中并没有这个目录

麻烦重新打下tag

这部分代码进行fair改造。当然并没有一次性全部代码改为fair，而是将 item抽取为一个widget。代码如下

fair对应的json

{
  "className": "Container",
  "na": {
    "height": 216,
    "width": 400,
    "child": {
      "className": "ListView",
      "na": {
        "padding": {
          "className": "EdgeInsets.only",
          "na": {
            "top": 0,
            "bottom": 0,
            "right": 16,
            "left": 16
          }
        },
        "scrollDirection": "#(Axis.horizontal)",
        "children": {
          "className": "Sugar.map",
          "pa": [
            "#(MealsListData.tabIconsList)"
          ],
          "na": {
            "builder": {
              "className": "MealsView",
              "na": {
                "mealsListData": "^(item)"
              }
            }
          }
        }
      }
    }
  },
  "methodMap": {}
}

对应的js

GLOBAL['#FairKey#']=(function(__initProps__){const __global__=this;defineModule(1,function(__mod__){with(__mod__.imports){function MealsView(){const inner=MealsView.__inner__;if(this==__global__){return new MealsView({__args__:arguments});}else{const args=arguments.length>0?arguments[0].__args__||arguments:[];inner.apply(this,args);MealsView.prototype.ctor.apply(this,args);return this;}}MealsView.__inner__=function inner(){StatelessWidget.__inner__.call(this);this.mealsListData=null;};MealsView.prototype={ctor:function ctor({key,mealsListData}={}){const __thiz__=this;const __arg_ctx__={key,mealsListData,};with(__thiz__){with(__arg_ctx__){this.mealsListData=mealsListData;StatelessWidget.prototype.ctor.call(__thiz__,key:key);}}},};inherit(MealsView,StatelessWidget);}__mod__.exports.MealsView=MealsView;},[]);return runCallback(function(__mod__){with(__mod__.imports){function _MealsListViewState(){const inner=_MealsListViewState.__inner__;if(this==__global__){return new _MealsListViewState({__args__:arguments});}else{const args=arguments.length>0?arguments[0].__args__||arguments:[];inner.apply(this,args);_MealsListViewState.prototype.ctor.apply(this,args);return this;}}_MealsListViewState.__inner__=function inner(){};_MealsListViewState.prototype={};_MealsListViewState.prototype.ctor=function(){Object.prototype.ctor.call(this);};;return _MealsListViewState();}},[1]);})(convertObjectLiteralToSetOrMap(JSON.parse('#FairProps#')));
