CodePudding user response：

   <View style={styles.circle}>
                    <Text style={styles.pinText}>{1}</Text>
                  </View>
                </Marker>
              ))
            : ''}

: ''} <= this part will be considered as text by system but no tag ,if you want to not return anything use null instead

   <View style={styles.circle}>
                    <Text style={styles.pinText}>{1}</Text>
                  </View>
                </Marker>
              ))
            : null}
