The text value of the MaterialTextField changes.

Reproduction steps

        <!-- Place new controls here -->
        <ui:MaterialTextField x:Name="txt1"></ui:MaterialTextField>

We recently started getting this issue, not sure why now all of a sudden, but based on forum search it might be related to a Xamar.iOS update. So with some guidance from other users in the forum I fixed it like this:

private void SetTextFieldValues(List<MaterialSetter> controls)
Device.BeginInvokeOnMainThread(() =>
controls.ForEach(x =>
x.MaterialTextField.SetBinding(MaterialTextField.TextProperty, new Binding($"BindingContext.{x.Value}", source: this));

class MaterialSetter

public MaterialSetter(MaterialTextField materialTextField, string value)
MaterialTextField = materialTextField;
Value = value;

public MaterialTextField MaterialTextField { get; }
public string Value { get; }

And this is how I call it:
SetTextFieldValues(new List<MaterialSetter>
new MaterialSetter(FullName, "Details.FullNames"),
