How to

Customize the thickness of stroke

The border stroke width (for Outlined) and line thickness (for Filled and None) can be customized based on the focus state of the input view by setting the FocusedStrokeWidth and UnfocusedStrokeWidth properties.

<inputLayout:SfTextInputLayout
            Hint="Name" 
            ContainerType="Outlined"
            HelperText="Enter your name"
	    FocusedStrokeWidth="4"
	    UnfocusedStrokeWidth="2">
            <Entry />
</inputLayout:SfTextInputLayout>
var inputLayout = new SfTextInputLayout();
inputLayout.Hint = "Name";
inputLayout.ContainerType = ContainerType.Outlined;
inputLayout.HelperText = "Enter your name"
inputLayout.FocusedStrokeWidth = 4;
inputLayout.UnfocusedStrokeWidth = 2;
inputLayout.InputView = new Entry();
