我想要一个 cupertino 风格的 Listtile/Card 或者我可以在我的 flutter 应用程序中使用的东西

Question

我正在写一个 flutter 应用程序并做一个日历视图应用程序。在首页上应显示所有日历项目。包括日期、标题、地点和时间。问题是我找不到适合这种库比蒂诺风格的列表块或卡片。我尝试了带有 listtile 或仅带有 listtile 的普通卡片，但我无法生成漂亮的 cupertino 风格小部件。你对我有什么建议吗？

Answer 1

Material Design 3 引入了新型卡片。这些可以通过配置 Card 小部件的属性来生成。

要使用此代码示例创建本地项目，请运行： 颤振创建 --sample=material.Card.3 mysample

之后你可以把你的日历放在新风格的卡片上。
