Unable to remove Flutter TextField input character to list list?

I added a TextField normal controls, listening input

OnChange (value) {

List The list=value. The split (' ');

Print (' pre is' + list. The toString ());

List. The removeAt (1);

//list. RemoveRange (0, 1);

Print (' the result is' + list. The toString ());

}

Remove the back of the print still cannot print, pure Dart run there is no problem,

Thanks to two, mainly because after the split is fixed length arrays, can't delete, two upstairs means new a new array, add in,
