+### Custom font with textStyle ( bold | italic | normal )
+copy fonts to assets folder by following the name pattern (example for font Roboto)
+```
+ Normal => fonts/<FontName>-Regular.<Font Extension> (eg:- fonts/Roboto-Regular.ttf)
+ Bold => fonts/<FontName>-Bold.<Font Extension> (eg:- fonts/Roboto-Bold.ttf)
+ Italic => fonts/<FontName>-Italic.<Font Extension> (eg:- fonts/Roboto-Italic.ttf)
+ BoldItalic => fonts/<FontName>-BoldItalic.<Font Extension> (eg:- fonts/Roboto-BoldItalic.ttf)
+```
+use `fonts/<FontName>.<Font Extension>` ( eg:- `fonts/Roboto.ttf`) as value for your style/view/theme fontPath attribute.And make sure that there is no actual file with name `fonts/<FontName>.<Font Extension>` ( eg:- `fonts/Roboto.ttf`) in the assets folder
