Answer 1

try this
class _QuizPageState extends State<QuizPage> {
List<Widget> scoreKeeper = [];
List<String> questions = ["First ques", "seacond ques", "third ques"];
#override
Widget build(BuildContext context) {
return Column(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
const Expanded(
flex: 5,
child: Padding(
padding: EdgeInsets.all(10.0),
child: Center(
child: Text(
questions[0], //why its not displaying "first ques"
textAlign: TextAlign.center,
style: TextStyle(
fontSize: 25.0,
color: Colors.white,
),
),
),
),
),
the reason you are getting error is that the Text widget takes only one string and you are passing two string to it.

Answer 2

First, you should remove const from the Expanded widget because you're using a variable inside on Text which is questions[0].
And I want to mention that its better to use questions.first for readability proposes and check if the list is empty before it to prevent possible errors.
So Here's the final result:
Column(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
Expanded(
flex: 5,
child: Padding(
padding: const EdgeInsets.all(10.0),
child: Center(
child: Text(
questions.first,
//why its not displaying "first ques"
textAlign: TextAlign.center,
style: const TextStyle(
fontSize: 25.0,
color: Colors.white,
),
),
),
),
),
],
),
