I basically want to decrease the size of the drawer in my Xamarin forms UWP app. I have a FlyoutPage and a Custom Renderer for that but i can't find the property of the size of the drawer. I guess i'm totally lost on Xamarin Forms because i'm a beginner and non-native english speaker.
So, here are my codes:
FlyoutMenuPage.xaml
'''
<?xml version="1.0" encoding="UTF-8"?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:local="using:FlyoutPageNavigation"
x:Class="FlyoutPageNavigation.FlyoutMenuPage"
Padding="0,20,0,0"
IconImageSource=""
Title="Random"
>
<StackLayout >
<ListView x:Name="listView" x:FieldModifier="public">
<ListView.ItemsSource>
<x:Array Type="{x:Type local:FlyoutPageItem}">
<local:FlyoutPageItem Title="Menu" IconSource="" TargetType="{x:Type local:BasePage}" />
<local:FlyoutPageItem Title="Settings" IconSource="" TargetType="{x:Type local:SettingsPage}" />
<local:FlyoutPageItem Title="Information" IconSource="" TargetType="{x:Type local:InformationPage}" />
</x:Array>
</ListView.ItemsSource>
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<Grid Padding="5,10">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="10"/>
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Image Source="{Binding IconSource}" />
<Label Grid.Column="1" Text="{Binding Title}" />
</Grid>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackLayout>
</ContentPage>
'''
Custom Renderer
i tried to add some code in here for the drawer size but nothing works so i deleted everything.
'''
[assembly: ExportRenderer(typeof(FlyoutMenuPage), typeof(FlyoutCustomRenderer))]
namespace Random.UWP.Custom_Renderers
{
class FlyoutCustomRenderer : PageRenderer
{
protected override void OnElementChanged(ElementChangedEventArgs<Page> e)
{
base.OnElementChanged(e);
if (e.OldElement != null || Element == null)
{
return;
}
}
}
}
'''
Thanks.

You can try this at the top of AppShell.xaml for example 360
FlyoutWidth="360"
Like this :

If you need a none-Shell project ,you can refer to the following solution .
FlyoutPage was renamed from MasterDetailPage , and I found the solution here , it used to work when it is named as MasterDetailPage , so I made a little modification , and it works now .
Add the following style into App.xaml in UWP project .
And OpenPaneLength repensents the width of the drawer , you can modify the value .
