How to disabled ListTile?-CodePudding

I need to disable the ListTile when at least one character is entered into the text field. I wrote the code, but I don’t understand how to write a function for onChanged. How can I do this?

bool _isEnableTile = true;

ListTile(
 ...
  onTap: _isEnableTile
      ? () => _selectPosition(_positionsList![index].id)
      : null,
);

TextField(
  onChanged: _onChangedPosition,
),

void _onChangedPosition(text) {}

Try This if you got any error let me know.

bool isAble=true;
ListTile(
            title: const Text("Lable"),
            enabled: isAble,
          ),
          TextField(
            onChanged: (value) {
              if (value.length > 0) {
                setState(() {
                  isaAble = false;
                });
              }
            },
          )
