use generate dynamic children, then create a data type tied to the app state or dynamic query, then when you generate the item from your list either firebase query or list of local state variables, add \"filter list items\" that takes a Boolean value, and the Boolean will be conditional if/else of \"if dropdown/choicechips/switch value/ is set and non-empty then make the filter equal to set dropdown/choice chips/switch value\" i'll attach some pictures to speed you up. Sorry if my answer is not helpful, English is not my first language.

My datatype, fields are \"Ujeedka\" which means in my case \"Category\" and type, createdAt, and some other values i want to filter my list

When user taps the Apply button to filter the list, the data type is created, populating from a widgets of filtering like choice chips and time picker, and other widgets. But the populating has some conditions attached. If the choice chips/time picker is set and not empty, then populate the datatype with the values of the widgets (choice chips, etc.), else make that field (e.g. the Type field of the dataType) Null. We'll use that null later in our filtreing.

In generating dynamic list, add filter list item and choose conditional value of if /then/else

Here is my filter list item logic, the logic basically says, \"if the Type/ujeedka/createdAt/or any field, is set and not empty, then make the the type/ujeedka/createdAt from my list im intending to filter, equal to type/ujeedka/createdAt field from my filteringLogic dataType. In that case if the user chose to filter using any of the filtering fields, it'll make the list filter in that field, and rest of field are null, so they won't affect the list. The \"Else\" value comes, make that true, so if any of the above conditions became false the list will populate without any filtering.

Here is my filtering bottom sheet, there is two buttons in the bottom of the column, sorry for my bad screenshotting skills. The apply button we already told what it'll do, but the cancel button, in my case, will make all of the filteringLogic dataType null.

Hope i atleast made a dent answering your question, i know your case is just \"filter and no filter\" functionality, but i hope you'll tailor this answer to your needs, if that means creating a logic that says \"if the textWidget is set and not empty then \"name\" equals to textWidget, else and the else value equals to true\".
