Set State not working with MultiSelectBottomSheetField

[Matthew-828]

Hi, I'm using MultiSelectBottomSheetField with other widgets that need setState like CheckboxListTile and Radio. When pressing the Radio button or checkBox ( or anything that is with setState ), it removes all the displaying item in the MultiSelectBottomSheetField. The variable still have the selected values but display all gone.

Hello,

I did try to reproduce this, but I'm not having the same problem. Can you provide a code example that reproduces the issue?

Hi Below is my code:

Under the stateful widget I declared the folowing variable.

Inside my Stateful widget -> body -> Form, I have a Future builder where future is "_getGroup", the variable declared in the first image to get API data. If snapshot has data, I convert the json data into list so that I can map it to MultiSelectItem. Then I do the MultiSelectBottomSheet as usual.

For your information, the ReportInfo class is as follows:

and this is how I get the _list

When I select the data, it looks like this:

but when I click on Radio / CheckBoxListTile, the chipDisplay is gone

I'm facing the same error when I use filtering search, it returns me setState error and clear all my selection.

Add the parameter key: GlobalKey() to your MultiSelectBottomSheetField and the setState will work
