我需要得到問題和答案，這些問題和答案在我的地圖列表中，其他地圖由 class 和構造函數制成

Question

我需要在列表視圖生成器中獲取問題和答案，該生成器位於我的地圖列表中，其他地圖由 class 和構造函數制成。 請幫我找出答案

ListView.builder(
                itemCount: examlist.length,
                itemBuilder: (BuildContext context, int index) {
                  return Card(
                    child: ListTile(
                      contentPadding: EdgeInsets.all(20),
                      title: Text(
                        examlist[index].title,
    
                        **//HERE I NEED TO PUT QUESTIONS
                        //HERE I NEED TO PUT ANSWERS**
                      ),
                      subtitle: Text(
                        examlist[index].desc, 
                      ),
                    ),
                  );
                },
              ),
            );

這是我的列表，其中包含根據 class 和構造函數的描述和標題以及問題和答案

List<Examlist> examlist = [
        Examlist(
            title: 'G.C.E A/L E-Tech Tamil - 2022',
            desc:
                'GCE A/L ICT  Unit Exam Papers Tamil Medium 2020  (New Syllabus). You can download using the following link Below. It’s free to download.',
            quesans: [
              {
                'question':
                    'Confidence intervals are useful when trying to estimate',
                'answer': 'unknown parameters',
              }
            ]),
        Examlist(
            title: 'G.C.E O/L Islam Tamil - 2022',
            desc:
                'GCE A/L ICT  Unit Exam Papers Tamil Medium 2020  (New Syllabus). You can download using the following link Below. It’s free to download.',
            quesans: [
              {
                'question':
                    'Confidence intervals are useful when trying to estimate',
                'answer': 'unknown parameters',
              }
            ]),
      ];
