I\'ve upgraded from RN 0.54 to 0.57 and my app has pretty much fallen over due to using React Native Elements.
I took use of their error functionality on TextI
TextI
In my case, this error occurred due to the presence of semi-colon ';' at the end of the closing of Text tag. For all those who don't get the appropriate answer above, try this. By removing semi-colon, the error disappeared.
