            });
  
            if(!pickerResult.cancelled){
              //this.setState({userImage: pickerResult.uri, imageResult : pickerResult, imageSelected: true});
              this.uploadImage(pickerResult.uri,'front-image')
              .then(()=&gt;{
                  alert('success');
              })
              .catch((error)=&gt;{
                  alert(error)
              });
