React Native add bold or italics to single words in Text field

Question

How do I make a single word in a Text field bold or italics  Kind of like this    lt Text gt This is a sentence  lt b gt with lt  b gt  one word in bold lt  Text gt    If I create a new text field for the bold character it will separate it onto another line so that s surely not the way to do it  It would be like creating a  lt  p   tag within a  lt  p   tag just to make one word bold

It is not in a text field as asked but wrapping separate text elements into a view would give the desired output  This can be used if you don t want to add another library into your project just for styling a few texts    lt View style   flexDirection   row    gt    lt Text style   fontWeight   700   marginRight  5   gt Contact Type  lt  Text gt    lt Text gt  data type  lt  Text gt   lt  View gt    Would result as follows

You could just nest the Text components with the required style  The style will be applied along with already defined style in the first Text component   Example     lt Text style  styles paragraph  gt     Trouble singing in   lt Text style   fontWeight   bold    gt  Resolve lt  Text gt    lt  Text gt

You can also put a Text tag inside of another Text tag  The second text tag will inherit the styling of the first  but you maintain the ability to style it independently from its parent   lt Text style  styles bold  gt Level        lt Text style  styles normal  gt Easy lt  Text gt   lt  Text gt     in your stylesheet       bold        fontSize  25      fontWeight   quot bold quot       color   quot blue quot          normal         will inherit size and color attributes     fontWeight   quot normal quot

I am a maintainer of react-native-spannable-string  Nested  lt Text  gt  component with custom style works well but maintainability is low   I suggest you build spannable string like this with this library   SpannableBuilder getInstance   fontSize  24         append  Using         appendItalic  Italic        append   in Text        build

Nesting Text components is not possible now  but you can wrap your text in a View like this    lt View style   flexDirection   row   flexWrap   wrap    gt       lt Text gt            Hello         lt  Text gt       lt Text style   fontWeight   bold    gt            this is a bold text         lt  Text gt       lt Text gt          and this is not      lt  Text gt   lt  View gt    I used the strings inside the brackets to force the space between words  but you can also achieve it with marginRight or marginLeft  Hope it helps
