FastLineSeries onRendererCreated ChartSeriesController

[Peter]

Hi

I have a Future<Builder> that calls a function to reload Chart data and I have MANY FastLineSeries.

When I create the FastLineSeries, I made use of

onRendererCreated: (ChartSeriesController controller) {

_mySeriesControllerList.add(controller);

}

_mySeriesControllerList is a list of controllers

I need a way to check if _mySeriesControllerList already have the same controller so won't add the same controll

This is because every time I update the chart, new controllers are added into _mySeriesControllerList
So, the first time, it is 24, then the next 48, and so forth

How do I address the issue?

We will resolve this and include the changes in our upcoming weekly patch release which is expected to be rolled out by 2^nd November 2021. We will update you once the release is rolled out and we appreciate your patience until then.
