Parsing number in flutter/dart

Question

I'm trying to parse the string "78,74"(which is a valid number in Brazil's format) to double, but I'm getting Format Exception and I can't find any way to parse it... Already searched in intl docs but there's nothing helpful.

I don't want to replace the "," with "." because i think that it must be a way to parse it using CultureInfo

My code is like

String x = "78,74";

double d = double.tryParse(x)

By default it is the way double.tryParse(x) behaving. I dont know something like that you are mentioning exist with yet Flutter(not sure). Why cant you replace comma if exist and replace it with dot and parse using replaceAll — Blasanka

Yeah, after more research I think that its the only way... Using replaceAll did the job — Caio Borghi

You can use double d = NumberFormat('pt_Br').parse(x) from intl library. You will need to add the dependencies.

The locale is the 2nd parameter : NumberFormat('', 'pt_Br').parse(x) works

Localization support for parsing numbers can be found in package:intl. For this particular case, you're looking for the parse method from NumberFormat.
