谁能详细解释这段代码发生了什么，我卡住了

Column(
  children: [
    Question(
      questions[_questionIndex]['questionText'],
    ),
    ...(questions[_questionIndex]['answers'] as List<String>)
        .map((answer) {
      return Answer(_answerQuestion, answer);
    }).toList()
  ],
)

请帮帮我，提前谢谢

Answer 1

Column( 
  children: [ 
    Question( questions[_questionIndex]['questionText'], ), ...   

    ( // I guess this brace should not be here

     questions[_questionIndex]['answers'] as List).map((answer) { 
        return Answer(_answerQuestion, answer); 
     }).toList() 
  ], 
)

所以 Column 存在一个 Question 小部件和一些 Answer 小部件。您需要更多详细信息吗？
