Flutter 颤振-如何确保即使在单击后退按钮后开关仍处于打开状态？
我有一个带有8个listTiles的设置菜单，如果我打开其中一个开关，问题是-当我单击“上一步”按钮并再次单击“设置”菜单时，开关关闭。。。即使单击了后退按钮，我还需要添加什么来确保开关处于打开状态 在这之后-what ever开关打开，这就是我想在另一个类中显示的彩色图像。。。。。这就是为什么我需要确保一次只打开一个开关，并且一旦用户单击后退按钮并单击返回到设置页面，开关仍然打开。。。我该怎么做这两件事呢Flutter 颤振-如何确保即使在单击后退按钮后开关仍处于打开状态？,flutter,dart,flutter-layout,flutter-dependencies,Flutter,Dart,Flutter Layout,Flutter Dependencies,我有一个带有8个listTiles的设置菜单，如果我打开其中一个开关，问题是-当我单击“上一步”按钮并再次单击“设置”菜单时，开关关闭。。。即使单击了后退按钮，我还需要添加什么来确保开关处于打开状态 在这之后-what ever开关打开，这就是我想在另一个类中显示的彩色图像。。。。。这就是为什么我需要确保一次只打开一个开关，并且一旦用户单击后退按钮并单击返回到设置页面，开关仍然打开。。。我该怎么做这两件事呢 导入“dart:ui”； 导入“package:Quran_highlighter/W
