Can't show variable value in a Text widget (Flutter)

Question

I have the following code:

_places.forEach((element) {
  final String name = element.name;
  print(element);
  places.add(Card(
      child: InkWell(
          splashColor: Colors.blue.withAlpha(30),
          onTap: () {
            print('Card tapped.');
          },
          child: const SizedBox(
              width: 375,
              height: 100,
              child: Padding(
                padding: EdgeInsets.all(15.00),
                child: Text(
                  name
                )
              )))));
});

The problem I'm having is that the variable name is giving an error when using it inside Text.

Error: Not a constant expression.

Please try removing the const from SizedBox. SizedBox expecting data to be constant, but the variable text can change on runtime. const is used in a case the value is constant from compile time.
