Expected behaviour

Picker does not throw a Maximum update depth executed error.

Actual behaviour

Picker throws Maximum update depth executed error

Steps to reproduce

Removing this code will not give the error, but I need to use a picker.

                                    <Item picker>
			              <Picker
			                mode="dropdown"
			                iosIcon={<Icon name="arrow-down" />}
			                style={{ width: undefined }}
			                placeholder="country"
			                placeholderStyle={{ color: "#bfc6ea" }}
			                placeholderIconColor="#007aff"
			                selectedValue={this.state.country}
			                onValueChange={this.onCountryChange.bind(this)}
			              >
			                <Picker.Item label="Canada" value="Canada" />
			                <Picker.Item label="United States" value="United States" />
			              </Picker>
			            </Item>

Is the bug present in both iOS and Android or in any one of them?
