How to add integer as default/initial value for TextFormField in flutter?

Question

This will work

TextEditingController _controller = new TextEditingController(text:"this works");

but this does not

TextEditingController _controller = new TextEditingController(text:123);

It shows this error:

The argument type 'int' can't be assigned to the parameter type 'String'.

But I’m not able to change the type to int for TextFormField.

Answer 1

TextEditingController only accepts String, so you have to convert your number to String.

TextEditingController _controller = new TextEditingController(text:123.toString());

or

TextEditingController _controller = new TextEditingController(text:"123");
