How to display json data in flutter charts

[Eti V.]

The title says it, knows anyone an example for how to display data you got from a http request  or can help with this?

thank you.

You need to be more specific on where you are having problems. You will have to convert the JSON data to a form that the particular chart library is expecting. The chart library will not know anything about JSON data, nor should it.

I guess this "You will have to convert the JSON data to a form that the particular chart library is expecting" is my biggest issue.

You need to break it up into several development steps.

First you need to figure out how to generate the particular style of chart you want in the chosen chart library using some hardcoded data. You did not specify which chart library you are trying to use, but charts_flutter is an official one from Google.

Any good chart library is going to have examples of how to generate each type of chart (e.g. here are the examples from charts_flutter). Start with the example code for the particular chart you want and tweak it to appear how you want with some hardcoded data.

Doing that you should have a good idea what form of input the chart needs then it is just a matter of reading the JSON and converting it into that form. See this for help in how to handle JSON in flutter.
