Hi Endrit,
I have used Apache ECharts with ionic (both UIWebView and WKWebView)
but found no memory problems.
I would suggest you not using flutter_echarts but use ECharts by itself
so that it can help you debug if it's the problem of ECharts
or flutter_echarts.
A few tips that may help:
Call "chart.dispose()" when the page destroys. For example, I'm using
Angular
so it looks like:
ngOnDestroy() {
if (this.chart) {
this.chart.dispose();
this.chart = null;
}
}
You should do something similar with flutter.
Thanks
