You can simply use something like this:
你可以简单地使用这样的东西：
yourMahAppFlyout.IsOpen = true;
Also you can bind the Flyout visibility to a WindowCommand(LeftWindowCommand/RightWindowCommand) so whenever you close the Flyout you can reopen using a ToggleButton(for example) from the top of the window.
您还可以将 Flyout 可见性绑定到WindowCommand( LeftWindowCommand/ RightWindowCommand)，因此无论何时关闭 Flyout，您都可以使用ToggleButton（例如）从窗口顶部重新打开。
<Controls:MetroWindow.Flyouts>
<Controls:FlyoutsControl>
<Controls:Flyout x:Name="yourMahAppFlyout"/>
</Controls:FlyoutsControl>
</Controls:MetroWindow.Flyouts>
<Controls:MetroWindow.RightWindowCommands>
<Controls:WindowCommands>
<ToggleButton Content="Layers"
IsChecked="{Binding ElementName=yourMahAppFlyout, Path=IsOpen}" Cursor="Hand"/>
</Controls:WindowCommands>
</Controls:MetroWindow.RightWindowCommands>
