showDlg<T> method

Future<T?> showDlg<T>(
  1. Widget widget, {
  2. bool barrierDismissible = true,
  3. Color? barrierColor = Colors.black54,
  4. dynamic result,
})

var app1 = await widget.manager.showDlg；则系统认为T是Object？ var app1; app1 = await widget.manager.showDlg；则系统认为T是dynamic; App app1 = await widget.manager.showDlg；则系统认为T是Future

Implementation

Future<T?> showDlg<T>(Widget widget, {bool barrierDismissible = true, Color? barrierColor = Colors.black54, dynamic result}) =>
    (Future.value(() as T));
