onSubmitted uses for when you press enter key, which triggers the callBack function(like print or other function).

TextField(
              onSubmitted: (value){
                print(value);
              },
            ),

CodePudding user response：

onSubmitted property called when the user indicates that they are done editing the text in the field.

Simply when user press Enter on keyboard and while using TextField, it calls onSubmitted, it provides the value of that TextField. Suppose, we don't have any TextEditingController or using onChanged and we can use setState method to assign the value here. I only prefer it when I just concern about final value.
