Description

Hi..

I am reporting an issue concerning TextInput in Android where fontFamily not changing on state changes..

Scenario :

• on Initial component load i am using normal fontFamily (using state) to display place holder. (Working Fine)
• When enter value in textField then fontFamily state should change & display Bold text. (Working Fine)
• Again if I remove values from the textfield & if the text field value is empty then the state should update to normal fontFamily (Not Working - i can see state is updated but view is not changing)
• Again enter value in the textfield It should show bold fontFamily but it showing the unknown fontFamily

When inspecting the changes State and Style are changing perfectly.. Not sure the problem in the view

Initial Load :

if value is not empty:

After Clearing the input Field:

Note : However in IOS all these things working fine.

Font Family used:  "Montserrat-ExtraBold",  "Montserrat-Medium";
