条件语句对2个函数进行分类（在firebase/Flutter中使用字段值）
问题描述 投票：0回答：1
我希望条件语句将集合中“dropdowncompany”字段数据的 2 个函数分类为“pr_details”，因此它们是该字段中的两个值
- "dropdowncompany":"ซินเนติก"
- "dropdowncompany":"ซินโนวิค"
-----示例图片---------
我真正需要的是条件语句函数
- if ("dropdowncompany" == "ซินเนติก") --> return 函数名称为“OverviewPurchase()”（公司名称与蓝色框同步）
- if ("dropdowncompany" == "ซินโนวิค") --> 返回函数名称为“OverviewPurchase1()”（带有绿色框的公司名称 Synovic）

很难理解你的问题。根据我的理解，如果companyName = 'A'，则在蓝色容器中显示数据，如果companyName = 'B'，则在绿色容器中显示数据。 我在这两个文件中运行了差异检查器，唯一的区别是颜色和标题。
color: document["dropdowncompany"] == 'ซินเนติก' ? Colors.lightBlueAccent[100] : Colors.lightGreenAccent[100],
这是要做的改变。您可以对标题进行类似的更改。另外，您不需要制作 2 个小部件。只需要1个
