Justify Self ❔
Custom alignment for individual items (Native workaround for the CSS equivalent).
How
Adding flexDirection to a component's style determines the primary axis of its layout.
Adding alignItems to a component's style determines the alignment of children
along the secondary axis (if the primary axis is row, then the secondary is column, and vice versa).
Workaround
Summary
So the best solution is two wrap the element which you want to apply justifySelf with a <View /> component
and apply flexDirection to the parent and get the desired alignment using align or justify.
