我的应用程序中有几个小部件，它们通过Map数据构建“卡片”（ListTiles），如下所示：

return FutureBuilder<List<MyCard>>(
                future: MyCard.readData(snapshot.data),
                builder: (context, cards) {
                  if (cards.hasData) {
                    final card = cards.data!;
                    return Expanded(
                        child: ListView(
                            padding: const EdgeInsets.all(16),
                            children: card.map(MyCard.buildCard).toList()));
                  } else {
                    return const Text("No data");
                  }
                });

方法buildCard（用于MyCard类）如下所示：

static Widget buildCard(MyCard card) {
    var dateFormat = DateFormat('MM/dd/yyyy');
    return Column(
      children: [
        Align(
            alignment: Alignment.centerRight,
            child: Text(dateFormat.format(card.createdOn.toDate()))),
        const SizedBox(height: 6),
        ListTile(
          shape:
              RoundedRectangleBorder(borderRadius: BorderRadius.circular(30)),
          tileColor: Colors.white,
          leading: CircleAvatar(child: Text(card.subCategory)),
          title: Text("Score: " + card.score + " Misses: " + card.misses),
          subtitle: card.comment.isNotEmpty
              ? Text("Comment(s): " + card.comment)
              : null,
          trailing: IconButton(
              icon: const Icon(Icons.arrow_forward_ios),
              onPressed: checkCard(card)), //need to pass context to checkCard
        ),
        const SizedBox(height: 18),
      ],
    );
  }

但是我需要将上下文传递给buildCard方法（因为我需要将它传递给checkCard方法，因为我试图在该方法中调用showDialog（），但我不知道如何传递上下文）。
我尝试简单地将BuildContext字段添加到buildCard方法中，如下所示：

static Widget buildCard(MyCard card, BuildContext context) {
    var dateFormat = DateFormat('MM/dd/yyyy');
    return Column(
      children: [
        Align(
            alignment: Alignment.centerRight,
            child: Text(dateFormat.format(card.createdOn.toDate()))),
        const SizedBox(height: 6),
        ListTile(
          shape:
              RoundedRectangleBorder(borderRadius: BorderRadius.circular(30)),
          tileColor: Colors.white,
          leading: CircleAvatar(child: Text(card.subCategory)),
          title: Text("Score: " + card.score + " Misses: " + card.misses),
          subtitle: card.comment.isNotEmpty
              ? Text("Comment(s): " + card.comment)
              : null,
          trailing: IconButton(
              icon: const Icon(Icons.arrow_forward_ios),
              onPressed: checkCard(card, context)),
        ),
        const SizedBox(height: 18),
      ],
    );
  }

但是当我试图将它传递给我的Widget中的方法时，它似乎不起作用。我想我应该按如下方式传递它：

return FutureBuilder<List<MyCard>>(
                future: MyCard.readData(snapshot.data),
                builder: (context, cards) {
                  if (cards.hasData) {
                    final card = cards.data!;
                    return Expanded(
                        child: ListView(
                            padding: const EdgeInsets.all(16),
                            children: card.map(MyCard.buildCard(context)).toList()));
                  }

但得到以下：
