Invariant violation while implementing dropdown list
0
Here I have made dropdown picker. I just want one reset button. When I click on reset button it should show the default value, not the selected and it should reset the chosen item.
I am experiencing an invariant violation with this code:
<Picker
style=width:'80%'
selectedValue=this.state.PickerValue
onValueChange=(itemValue,itemIndex) =>
this.setState(PickerValue:itemValue)
>
<Picker.Item label="Select a option" value=""/>
<Picker.Item label="About us" value="About us" />
<Picker.Item label="Help" value="Help"/>
</Picker>
</View>
);
}
}
const styles = StyleSheet.create(
container:
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
,
welcome:
fontSize: 20,
textAlign: 'center',
margin: 10,
,
instructions:
textAlign: 'center',
color: '#333333',
marginBottom: 5,
,
);
Can someone help me find my syntax error?

You removed the image.. If this is all the code, then you are closing a </View> without opening it. You should take a look into that

You removed the image.. If this is all the code, then you are closing a </View> without opening it. You should take a look into that
