i wrote this code for a registration page. in some phones, the screen doesn't fit for all the views so i used a scrollview so that the user could scroll down through them. the problem i'm facing is that the scrollview doesn't scroll enough upwards. the button at the end doesn't appear. here is my xaml code:
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"

i tried different things, i put the scrollview inside a contentview but i didn't work. what am i doing wrong?
You can try to add property RowDefinitions and define two row for the outer grid.
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="100" />
</Grid.RowDefinitions>
<!--other code-->
<Grid>
You can refer to the following code:
<ContentPage.Content>
<ScrollView Orientation="Vertical">
<ScrollView.Background>
<LinearGradientBrush EndPoint="0,1">
<GradientStop Color="#0d98ba"
Offset="0.2" />
<GradientStop Color="White"
Offset="1" />
</LinearGradientBrush>
</ScrollView.Background>
<StackLayout>
<Grid>
<!--add two row here-->
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="100" />
</Grid.RowDefinitions>
<StackLayout>
<Frame CornerRadius="50" BorderColor="White" BackgroundColor="Transparent" Margin="20,50">
