Flutter开发--------结合echart

前言

前一段时间，就在苦恼flutter的图标问题，今天逛github的时候，发现有人开发了一个插件来对接echert

准备工具

这套课程是采用VScode进行开发的。当前在此之前请准备好Flutter开发环境，我这里就不进行讲解了。

实现界面

首先是一个列表的展示

实例代码分析

这个实例使用到了flutter_echart插件。到pubspec.yaml中

dev_dependencies:
  flutter_test:
    sdk: flutter
  
  flutter_echart: 
    git:
      url: git://github.com/furuiCQ/flutter_echart.git

放置echart的文件

新建一个assets文件夹，里面放置echart.html，到pubspec.yaml中

assets:
    - assets/echart.html

主文件编写

import 'package:flutter/material.dart';
import 'package:flutter_echart/flutter_echart.dart';

void main() => runApp(MyApp());


class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => new _MyAppState();
}

class _MyAppState extends State<MyApp> {
  @override
  void initState() {
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    var option = {
      "xAxis": {
        "type": "category",
        "data": ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"]
      },
      "yAxis": {"type": "value"},
      "series": [
        {
          "data": [820, 932, 901, 934, 1290, 1330, 1320],
          "type": "line"
        }
      ]
    };

    return new MaterialApp(
      home: new Scaffold(
          appBar: new AppBar(
            title: const Text('Native WebView as Widget'),
          ),
          body: new SingleChildScrollView(
            child: new Column(
              children: <Widget>[
                new Text('Native WebView as Widget\n\n'),
                new Container(
                  child: EchartView(height: 300, data: option),
                  height: 300.0,
                  width: 500.0,
                ),
              ],
            ),
          )),
    );
  }
}

这篇博客是要是给大家分享这个插件，插件地址，我已经给GitHub编写者一个star，鼓励他继续开发这个插件。
