How can I hide letter counter at the bottom of TextBox in MaterialDesign

In latest version of MaterialDesign WPF this problem is showing.
Is there any property or something else to hide it?

• MaterialDesignThemes Version 4.0.0
• MaterialDesignColors Version 2.0.0

Code:

<TextBox materialDesign:HintAssist.Hint="First Name" FontSize="18" Style="{StaticResource MaterialDesignFloatingHintTextBox}" MaxLength="50"/>

There is already an issue on GitHub concerning how to hide the character counter.

• How disable CharacterCounter on TextBox

It is already confirmed that there will be a way to disable it in the upcoming release.

In the next release there will be a new attached property you can use to hide the character counter.

<TextBox
   MaxLength=""10""
   materialDesign:TextFieldAssist.CharacterCounterVisibility=""Collapsed""/>

In the meanwhile you can either downgrade to a previous version of MaterialDesign, as this feature was introduced in version 4.0 or you can use the workaround suggested in the issue.

<TextBox>
    <materialDesign:TextFieldAssist.CharacterCounterStyle>
        <Style TargetType="TextBlock" />
    </materialDesign:TextFieldAssist.CharacterCounterStyle>
</TextBox>
