Question:

How to Dynamically Control the hintText in a TextField in Flutter?

To dynamically Control the hintText in a TextFIeld in Flutter, you can use the following code.

Omit the provider (and maybe even the controller), and change the hintText every time the user completes some input by pressing "enter":

TextField(

onSubmitted: (String text) => setState(() {

hintText = text;

}),

decoration: InputDecoration(

border: InputBorder.none, // Remove underline

hintText: hintText, // Add prompt text

hintStyle: TextStyle(

fontSize: 17,

color: Colors.grey.withOpacity(0.7),

controller: TextEditingController(),

and a controller without the provider:

final taskEditingController = TextEditingController();

and the hintText attibute with initial hint to be overwritten:

String hintText = "math";
