Flutter - 事件/时间线预约排版问题

Question

这里是 Flutter 新手，

我们正在尝试创建一个简单的预约应用程序以在我们的诊所中使用，如果您能提供一些有关如何进行此操作的建议，我们将不胜感激。我已经包含了我们正在努力实现的模型 here .

我们需要多个列 - 每个医生工作一列，时间线显示固定在左侧的小时数。约会从 10 分钟到 1 小时不等，我们需要能够选择它们进行编辑。除此之外，能够选择一个单元格(即:双击以添加新约会)是我们想要实现的一项功能。此外，同一列中的约会不能重叠。

我们查看了以下内容:- Flutter 表格布局- 带有卡片的单独列(相对于预订时间对齐)- 自定义画家- 网格布局

我们已经下载了一些软件包，例如 SyncFusion 日历和时间线应用程序，并将它们分开。然而，在我们陷入困境之前，任何建议都会很棒。

谢谢你的时间
