Description

A native-flutter-hybrid develop tool helps you add and develop flutter with your existing app. We supports a standard hybrid project structure following google. We supports a fast intergration of flutter-boost which is a standard solution to manage native and flutter pages.

flutter-boot for sinanews.

Host app requirements

support flutter version ^1.5.0
commit all native code before using me :)

Installation

install from npm
```
npm install -g sn-flutter-boot
```
initialize flutter module Let's assume you have an existing Flutter environment, if you don't, please read Flutter Get Started run init command
```
flutter-boot init
```
then follow the instruction to complete the initialization
add flutter-boost In Android
- run use command in android project
```
flutter-boot use
```
- select FlutterBoost
- create a MyApplication class if your project does not have a custom application, then add it to AndroidManifest.xml
```
android:name=".MyApplication"
```
- insert the code below into the "onCreate" method in your application class
```
/// initialize the flutter boost
FBInitializer.init(this);
```
- insert the code below into the "onCreate" method in your Actvity class
```
/// add a button in native activity for navigating to flutter
FBViewEntry.setup(this);
```
In iOS
- change the super class of Appdelegate to FLBFlutterAppDelegate, import code:
```
#import <flutter_boost/FLBFlutterAppDelegate.h>

@interface AppDelegate : FLBFlutterAppDelegate <UIApplicationDelegate>
```
- insert the code below into the "application:didFinishLaunchingWithOptions" method in your Appdelegate.m
```
#import "FBDemoRouter.h"

[FBDemoRouter registerInFlutterBoost];
```
- insert the code below into your viewcontroller
```
#import "FBDemoRouter.h"
/// add a button in native controller for navigating to flutter
[[FBDemoRouter shared]addEntryView:self];
```
- run target Runner
your workmates do if you have prepared hybrid enviroment by flutter-boot, and your workmates want to develop flutter, then they should run flutter-boot link before running flutter.

Usage

run in native

Just run your app as normal

run in flutter

use 'flutter run' in your flutter project

How it works

command create

command create invokes the original flutter module creation command, then creates shell projects for flutter archiving, and prepares git environment. Changed files as below:

somepath/my_repo
└──my_android
└──my_ios
└──my_flutter
    └──.git
    └──.gitignore
    └──android_shell
    └──ios_shell
    └──android
    └──ios

command link

command link is used for linking native project and flutter project locally, you can run your app both in native and flutter after project linked.

Changed files as below:

somepath/my_repo
└──my_android
    └──fbConfig.local.json
    └──fbinclude_flutter.groovy
    └──build.gradle
└──my_ios
    └──fbConfig.local.json
    └──fbpodhelper.rb
    └──.xcworkspace
    └──Podfile
└──my_flutter
    └──.gitignore
    └──android symlink with my_android
    └──ios symlink with my_ios

The existed filed being modified

my_ios

.xcworkspace:

we copied a scheme named Runner, which is limited by flutter, from the scheme named by project

scripts added to build phase setting

"$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" build 
"$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" embed

Podfile:

# Created by flutter-boot
target 'Runner' do
  # Uncomment the next line if you're using Swift or would like to use dynamic frameworks
  # use_frameworks!

  # Pods for Runner

  target 'RunnerTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'RunnerUITests' do
    inherit! :search_paths
    # Pods for testing
  end


  eval(File.read(File.join(File.dirname(__FILE__), 'fbpodhelper.rb')), binding)

end

my_android

build.gradle:

    // [FLUTTER_DEPENDENCY_BEGIN] 
    if (gradle.isDetectedFlutterDir) { 
        implementation project(':flutter') 
    } else { 
        // 换成自己的远程flutter产物 
    }

setting.gradle:

// [FLUTTER_CONFIG_BEGIN]
setBinding(new Binding([gradle: this])) 
evaluate(new File('fbinclude_flutter.groovy')) 
// [FLUTTER_CONFIG_END]

gradle.properties:

android_enableDetectFlutterDir=true

command remotelink

command remotelink is to record your remote flutter git repository which will generate a shared config file. Changed files as below:

somepath/my_repo
└──my_android
    └──fbConfig.json
└──my_ios
    └──fbConfig.json
└──my_flutter

command update

command update will fetch your remote linked flutter repository into your native project. Changed files as below:

somepath/my_repo
└──my_android
    └──.fbflutter
└──my_ios
    └──.fbflutter
└──my_flutter

command use

use FlutterBoost

FlutterBoost dependency will be added and sample code will be added in android when use FlutterBoost. Changed files as below:

somepath/my_repo
└──my_android
    └──com.example.fbi.fb
└──my_ios
    └──tios
        └──fbi
            └──fb
                └──FBDemoRouter.h
                └──FBDemoRouter.m
└──my_flutter
    └──pubspec.yaml

command init

command init assembles a bunch of other commands that helps you build native-flutter hybrid developing enviroment smoothly.

简介

这是一个帮助你在已有原生应用的情况下，搭建flutter混合开发环境的工具。我们提供了标准的混合工程结构，同时支持混合栈（一套原生和flutter之前页面通信和过渡的方案）的快速接入。

安装的app必需

拥有^1.5.0的flutter环境
在使用前提交你所有待提交的代码

安装

从npm安装
```
npm install -g flutter-boot
```
我们假设你已经拥有了基础的flutter环境（如果没有可以参考Flutter Get Started），然后你可以使用以下命令来初始化你的混合工程
```
flutter-boot init
```
然后根据命令内的提示完成所有步骤
添加混合栈 Android应用
- 在android应用内运行
```
flutter-boot use
```
- 选择FlutterBoost
- 如果你的工程没有Application类，请创建自定义的Application类，然后把它添加到AndroidManifest.xml
```
android:name=".MyApplication"
```
- 将以下代码插入到Application类的"onCreate"方法内
```
/// initialize the flutter boost
FBInitializer.init(this);
```
- 将以下代码插入到你的Actvity类的"onCreate"方法内，来显示一个跳转flutter的视图
```
/// add a button in native activity for navigating to flutter
FBViewEntry.setup(this);
```
iOS应用
- 将Appdelegate的父类修改为FLBFlutterAppDelegate，参考如下代码:
```
#import <flutter_boost/FLBFlutterAppDelegate.h>

@interface AppDelegate : FLBFlutterAppDelegate <UIApplicationDelegate>
```
- 将以下代码插入在Appdelegate.m文件的"application:didFinishLaunchingWithOptions"方法中
```
#import "FBDemoRouter.h"

[FBDemoRouter registerInFlutterBoost];
```
- 将以下代码插在你的viewcontroller文件中，它会展示一个跳转flutter的入口按钮
```
#import "FBDemoRouter.h"
/// add a button in native controller for navigating to flutter
[[FBDemoRouter shared]addEntryView:self];
```
- 打开xcode，将scheme切换为Runner，然后运行即可
如果你的同事已经使用flutter-boot创建好了混合工程，而你又需要进行flutter开发，那么你需要的是在启动app前运行flutter-boot link来关联你的本地的flutter工程和native工程

使用

原生视角使用

像平时运行原生应用一样

flutter视角使用

像其他flutter开发者一样使用'flutter run'

它是怎么生效的

create命令

create命令调用了flutter module的创建命令，同时为了打包产物而创建了壳工程，然后提供了一个快速链接git仓库的方式。受影响的文件如下

somepath/my_repo
└──my_android
└──my_ios
└──my_flutter
    └──.git
    └──.gitignore
    └──android_shell
    └──ios_shell
    └──android
    └──ios

link命令

link命令是用来关联你本地的flutter工程和原生工程，这样你就同时拥有了两种开发视角.

受影响的文件如下:

somepath/my_repo
└──my_android
    └──fbConfig.local.json
    └──fbinclude_flutter.groovy
    └──build.gradle
└──my_ios
    └──fbConfig.local.json
    └──fbpodhelper.rb
    └──.xcworkspace
    └──Podfile
└──my_flutter
    └──.gitignore
    └──android symlink with my_android
    └──ios symlink with my_ios

已存在的文件修改记录如下

my_ios

.xcworkspace:

在目前的flutter环境下，我们根据与工程名称同名的scheme，复制了一份名为runner的

在build phase setting内添加了如下脚本引用

"$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" build 
"$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" embed

Podfile:

# Created by flutter-boot
target 'Runner' do
  # Uncomment the next line if you're using Swift or would like to use dynamic frameworks
  # use_frameworks!

  # Pods for Runner

  target 'RunnerTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'RunnerUITests' do
    inherit! :search_paths
    # Pods for testing
  end


  eval(File.read(File.join(File.dirname(__FILE__), 'fbpodhelper.rb')), binding)

end

my_android

build.gradle:

    // [FLUTTER_DEPENDENCY_BEGIN] 
    if (gradle.isDetectedFlutterDir) { 
        implementation project(':flutter') 
    } else { 
        // 换成自己的远程flutter产物 
    }

setting.gradle:

// [FLUTTER_CONFIG_BEGIN]
setBinding(new Binding([gradle: this])) 
evaluate(new File('fbinclude_flutter.groovy')) 
// [FLUTTER_CONFIG_END]

gradle.properties:

android_enableDetectFlutterDir=true

remotelink命令

remotelink命令用来记录你的flutter git仓库. 受影响的文件如下:

somepath/my_repo
└──my_android
    └──fbConfig.json
└──my_ios
    └──fbConfig.json
└──my_flutter

update命令

update命令会从远端拉取你的flutter仓库代码，然后放置在你的原生工程内. 受影响的文件如下:

somepath/my_repo
└──my_android
    └──.fbflutter
└──my_ios
    └──.fbflutter
└──my_flutter

use命令

使用FlutterBoost

FlutterBoost的依赖会被注入到flutter配置文件中，同时在android侧我们会添加一些示例代码. 受影响的文件如下:

somepath/my_repo
└──my_android
    └──com.example.fbi.fb
└──my_ios
    └──tios
        └──fbi
            └──fb
                └──FBDemoRouter.h
                └──FBDemoRouter.m
└──my_flutter
    └──pubspec.yaml

init命令

init命令是上述一些命令的功能集合，它能帮助你流程的完成整个混合工程的搭建。
