I want to know how to refresh a view when a sheet is dismissed, either by swiping down the sheet or clicking the close button.
I have a custom TabBarView that has a MicButtonView (this shows a circle button that when clicked shows a sheet)
Heres all my code for the TabBarView code. I also included the code for the ViewRouter. I'm trying to give a complete picture of what my code looks like so someone could help me with this?
struct TabBarView: View {
@StateObject var viewRouter: ViewRouter
@EnvironmentObject var dataController: DataController
@State var showPopUpMenu = false
@State private var showWhatsNewView = false
var body: some View {
GeometryReader { geo in
VStack {
Spacer()
// This is how we navigate
switch viewRouter.currentPage {
case .home:
ListOfRecordingsView(dataController: dataController)
case .settings:
SettingsView(dataController: dataController)
}
Spacer()
/// The TabBar
HStack {
Spacer()
TabBarIcon(viewRouter: viewRouter,
assignedPage: .home,
proxy: geo,
systemIconName: "folder",
tabName: "Recordings"
)
Spacer()
MicButtonView(showPopUpMenu: $showPopUpMenu, proxy: geo)
Spacer()
TabBarIcon(viewRouter: viewRouter,
assignedPage: .settings,
proxy: geo,
systemIconName: "gearshape",
tabName: " Settings "
)
Spacer()
}
.frame(width: geo.size.width, height: geo.size.height/Constants.flt8)
.background(Color.TabBarBackground.opacity(0.7))
} // End of VStack
/// This disables the sidebar
.navigationViewStyle(StackNavigationViewStyle())
.edgesIgnoringSafeArea(.bottom)
} // End of Geo Reader
.onAppear {
showWhatsNewView = dataController.checkForUpdate()
}
.sheet(isPresented: $showWhatsNewView) {
WelcomeScreenView(dataController: dataController)
}
}
}
/// This struct represents a single TabBar item
struct TabBarIcon: View {
@EnvironmentObject var dataController: DataController
@StateObject var viewRouter: ViewRouter
let assignedPage: Page
let proxy: GeometryProxy
let systemIconName, tabName: String
private let device = Device.current
var body: some View {
Spacer()
if device.isPad {
HStack {

.aspectRatio(contentMode: .fit)
.frame(width: proxy.size.width/Constants.flt14, height: proxy.size.height/Constants.flt28)

.genericTextModifier(

}
Spacer()
}
}
struct MicButtonView: View {
@EnvironmentObject var dataController: DataController
@Binding var showPopUpMenu: Bool
let proxy: GeometryProxy
private let device = Device.current
var body: some View {

.offset(

}
Here is the ViewRouter:
class ViewRouter: ObservableObject {
@Published var currentPage: Page = .home
}
enum Page {
case home
case settings
}
