Take Textformfield value in double

Question

How can I get the value of a Textformfield in double? I’ve created a Texteditingcontroller,

var controller = new TextEditingController();

but the controller.text comes in string and I can’t get it to double.

Answer 1

to receive :

controller.text = valor.toStringAsFixed(2); //para retornar com duas casas; 
controller.text = valor.toStringAsFixed(2).replaceAll('.', ','); //se quiser converter o ponto em virgula, padrao pt-br

to convert into double:

valor = double.tryParse(controller.text) + 0.00;// para nao pegar o valor em tipo dynamic
