Couldn't find version numbers for the following packages in the issue:

• npm
• expo

Can you update the issue to include version numbers for those packages? The version numbers must match the format 1.2.3.

If you want to make the under line transparent to make it disappear, you can do this:

underlineStyle={{ display:'none' }}
