How can I do math for values ​given in TextEditingController? – Flutter

    late final TextEditingController _weight = TextEditingController()
  late final TextEditingController _height = TextEditingController()

For example, for these two TextEditingControllers, I want to collect the values ​​entered by the user and print them in Text. How do I code this?

    You access the text by checking the text property. In your example, e.g.:

    _weight.text

    You can try to parse text property like this:

    final _weightValue = double.tryParse(_weight.text);
final _heightValue = double.tryParse(_height.text);

    I suggest you force keyboard to insert only numbers with:

    keyboardType: TextInputType.number

    in your TextField
