<FloatingLabelTextInput
                  containerStyle={{ width: '100%', height: 80, backgroundColor:'#000'}}
                  onChangeText={this.onChangeText}
                  placeholder={`Point`}
                  value={this.state.name}
                  maxLength = {8}
                  style={{color:'transparent'}}
                />
