解决方法
试试这个代码:
<StackLayout>
<Label Text=" Product Detail" Padding="10,10,0"/>
<StackLayout Padding="10" VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand">
<Frame HasShadow="False" VerticalOptions="Fill" CornerRadius="5" Padding="1" BackgroundColor="#000000">
<Frame HasShadow="False" CornerRadius="5" BackgroundColor="White" Padding="0">
<Grid Padding="10,0">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="7*"/>
<RowDefinition Height="2*"/>
</Grid.RowDefinitions>
<Label Text="Jeep Rubicon" Grid.Row="0"/>
<ffimageloading:CachedImage
Grid.Row="1"
x:Name="mainImage"

问题是由您设置的 WidthRequest="380"
和 HeightRequest="380"
引起的。
图片的高度大于宽度。
所以给一个合适的 WidthRequest 和 HeightRequest 将解决这个问题:
WidthRequest="320"
HeightRequest="480"
更新:
<Grid HorizontalOptions="FillAndExpand"
VerticalOptions="FillAndExpand">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<ffimageloading:CachedImage BackgroundColor="Red"
x:Name="mainImage"
Source="logo.jpg"
CacheDuration= "50"
RetryCount= "3"
RetryDelay= "600"
DownsampleToViewSize = "true"
Grid.Column="0"
Aspect="AspectFit">
</ffimageloading:CachedImage>
</Grid>
