如何在 Flutter CheckboxListTile 中设置像 HTML 这样的值？

Question

In HTML, checkbox has name, value and label:

<input type="checkbox" id="fruit" name="fruits" value="small_apple"><label for="fruit">Small Apple</label>
<input type="checkbox" id="fruit" name="fruits" value="big_apple"><label for="fruit">Big Apple</label>

If both are checked, I will get an array named fruits which contains "small_apple" and "big_apple" once submitted.

Flutter CheckboxListTile has a title which appear on screen:

CheckboxListTile(
    title: Text("Small Apple"),
    value: value,
    onChanged: (bool value) { ... },
)

I do not need "Small Apple" to be sent on submit, but "small_apple". "value" in Flutter keeps checkbox state(true/false) only, so how can I set "value" like HTML in Flutter? Or do I have to convert "Small Apple" to "small_apple" before submit?

Answer 1

Well you can declare a String String stringValue; and inside your onChanged callback you can set the needed value for each checkbox For example for the small_apple checkbox just add

onChanged:(ischecked){
stringValue = "small_apple" ;
value= ischecked;
}

And then do the same thing for the other checkbox, Now you must have to set the checkbox value inside the OnChanged And Call setState so the UI state of your checkbox changes
