Flutter has been applied to more and more massive projects, and complex data visualization charts has been an important requirement. Echarts is independent of any UI framework, but it is designed driven by data, and changes in data drive changes in the chart.

In flutter_echarts, we just need to connect the data driving method of ECharts with the view updating of Flutter to implement the widget's reactive updating.
