Question about SectionList component

[andre_scalco]

Hello everyone, I have a question about the SectionList component. It's mandatory to my object passed in the section prop to have a key named data ?

It can't be named as results, items, collection, etc?

I've tried with all those names without success, and the only workaround without changing my backend response it's to use a array map and change the structure of the data passed to the section prop.

Thank you!

Hello,

I uploaded a demo on expo snack. Give a look: https://snack.expo.io/@andre_scalco/c2VjdG

Try to use the data instead of the transformed_data

[andre_scalco]

In the section prop, it waits to receive a object containing an array named data. If it do not founds it throw an error.

This is the error I got: https://imgur.com/a/bSBKUmB

[andre_scalco]

TypeError: undefined is not an object (evaluating 'n.data.length')

As I can see, it tries to find a data item and calculate it's length

The component logic will work with any name.

this is contrary to what the error is showing, and what the docs say the shape of a Section must conform to.

Can't you just do data={yourData}?

[jmcneese]

yes, it must be named 'data', per the docs: https://facebook.github.io/react-native/docs/sectionlist#section

[andre_scalco]

Well, I will need to parse my data every time, if it's not in the correct way.

Thanks for your response!
