## README

# flutter_echarts

A new Flutter application.

## 1. Getting Started

```shell
# Android Studio plugins => https://plugins.jetbrains.com/

# 在项目目录下运行
flutter package get # flutter pub get
```



## 2. Issue

1. 初次运行卡在Running Gradle task 'assembleDebug' 解决方法：

修改flutter安装目录下，`/packages/flutter_tools/gradle/flutter.gradle`
`private static final String MAVEN_REPO = "https://storage.googleapis.com/download.flutter.io";`改为`private static final String MAVEN_REPO = "https://mirrors.tuna.tsinghua.edu.cn/flutter/download.flutter.io";`



## 3. Platform Channel

1. 首先在原生层android/app/src/main/java/的目录下，建立原生层的类，即./package_name/class_name;
2. CustomViewRegistrant 用于在原生的监听注册，这里注册时要注意通道值要和flutter的一致，确保在同一条通道上才可以交互;

```java
通讯机制，Platform Channel主要分三种：
 1.BasicMeaaspeChannel :大内存数据块传递的情况使用
 2.MethodChannel:传递方法的调用，通常情况下用
 3.EventChannel:数据流的通讯
这三种通讯在不同情况下使用，但是共同点都是通过BinaryMesage作为通讯工具
```
