  <pre><code> &lt;Bubble
                  {...props}
                  wrapperStyle={{
                      right: {
                          backgroundColor: colors.chatPurple,
                          borderRadius: 30,
                          borderBottomRightRadius: 30,
                          marginBottom: 10,
                          padding: 5,
                          right: 15,
                          justifyContent: "flex-end",
                          alignSelf: 'stretch',
                          marginLeft: 0,
                          alignSelf: "center"
                      },
                      left: {
                          backgroundColor: colors.lightGreen,
                          borderRadius: 30,
                          marginBottom: 20,
                          padding: 5,
                          left: -30
                      }
                  }}/&gt;
