XAML usage

In order to make use of sheet within XAML you can use this namespace:

'xmlns:bottomsheet="clr-namespace:Maui.BottomSheet;assembly=Maui.BottomSheet"'

BottomSheet is a View and can be added in any layout or control which accepts View. To open/close a BottomSheet simply set IsOpen property to true/false. You can have multiple BottomSheets on one page.

<bottomsheet:BottomSheet IsOpen="True">
    <bottomsheet:BottomSheet.ContentTemplate>
        <DataTemplate>
            <VerticalStackLayout>
                <Label Text="I'm a simple BottomSheet!"/>
            </VerticalStackLayout>
        </DataTemplate>
    </bottomsheet:BottomSheet.ContentTemplate>
</bottomsheet:BottomSheet>

Navigation

IBottomSheetNavigationService is be registered automatically and can be resolved by DI.

private readonly IBottomSheetNavigationService _bottomSheetNavigationService;

public MainViewModel(IBottomSheetNavigationService bottomSheetNavigationService)
{
  _bottomSheetNavigationService = bottomSheetNavigationService;
}

To navigate to a BottomSheet you have to register BottomSheets and ViewModels

builder.Services.AddTransient<BottomSheetVMViewModel>();
builder.Services.AddTransient<BottomSheetGoBackViewModel>();

builder.Services.AddTransient<IBottomSheet, BottomSheetNoVM>();
builder.Services.AddTransient<IBottomSheet, BottomSheetVM>();
builder.Services.AddTransient<IBottomSheet, BottomSheetGoBack>();

Navigate to a BottomSheet and wire it automatically to specified ViewModel or navigate to a BottomSheet without a ViewModel

_bottomSheetNavigationService.NavigateTo<BottomSheetNoVM>();
_bottomSheetNavigationService.NavigateTo<BottomSheetVM, BottomSheetVMViewModel>();

To close a BottomSheet simply call GoBack or ClearBottomSheetStack(if you have multiple sheets open and want to close all of them)

You can pass parameters on each navigation(this follows principle of shell navigation) Pass an instance of BottomSheetNavigationParameters to navigation and if target ViewModel implements IQueryAttributable parameters will be applied.

BottomSheet Builder

Open any ContentPage or View as BottomSheet

Use IBottomSheetBuilder to build a BottomSheet from a ContentPage or View. Use IBottomSheetBuilderFactory to create a new instance of IBottomSheetBuilder. By default both instance types are registered and can be resolved by DI(may change in future if custom services are needed!)

API

Usage

public MainViewModel(IBottomSheetBuilderFactory bottomSheetBuilderFactory)
{
    _bottomSheetBuilderFactory = bottomSheetBuilderFactory;
}

private void OpenContentPageAsBottomSheet()
{
    _bottomSheetBuilderFactory.Create()
    .FromContentPage<NewPageA>()
    .ConfigureBottomSheet((sheet) =>
    {
        sheet.SheetStates = BottomSheetState.All;
    })
    .WireTo<NewPageAViewModel>()
    .Open();
}

private void OpenViewAsBottomSheet()
{
    _bottomSheetBuilderFactory.Create()
        .FromView<ContentA>()
        .ConfigureBottomSheet((sheet) =>
        {
            sheet.SheetStates = BottomSheetState.Medium;
        })
        .WireTo<ContentAViewModel>()
        .Open();
}
