flutterとswiftでのhomewidget作成

@available(iOS 14.0, *)
struct WidgetEntryView: View {
    var entry: Provider.Entry

    var body: some View {
        if #available(iOS 17.0, *) {
            Text(entry.summaryContent)
                .padding()
                .containerBackground(for: .widget) 
        } else {
            Text(entry.summaryContent)
                .padding()
        }
    }
}

これを以下のように修正

@available(iOS 14.0, *)
struct WidgetEntryView: View {
    var entry: Provider.Entry

    var body: some View {
        if #available(iOS 17.0, *) {
            Text(entry.summaryContent)
                .padding()
                .containerBackground(.regularMaterial, for: .widget) // 修正箇所
        } else {
            Text(entry.summaryContent)
                .padding()
        }
    }
}
