First, the problem occurs under ios simulator (all virtual devices).
Dependencies: @remobile/react-native-toast": "^1.0.7" "react-native": "0.56.0"...
Description of the problem: I simulate an api error in an async method like that :
async getData() {
 await MyApi.myMethod(...).catch(() => {
   Toast.showLongTop(myToastMessage);
 });
 // Here a toast would be displayed correctly
 }
and the toast notification doesn't show itself, even if it does go through the .catch().
Thanks for your help!
 
                        
you made him wrong, try to make your toast like this
ToastAndroid.show('HI world', ToastAndroid.SHORT);
