undefined is not an object (evaluating newText.split)
1
I have an error I can't seem to work out. I am getting undefined is not an object (evaluating newText.split) when this code runs.
<View style={fieldContainerStyle}>
<TextInput
{...inputProps}
{...input}
onSelectionChange={(event) => this.setState({ cursorPosition: event.nativeEvent.selection, selection: event.nativeEvent.selection })}
onSubmitEditing={() => {
const { query, cursorPosition } = this.state;
let newText = query;
const ar = newText.split('');
ar.splice(cursorPosition.start, 0, 'n');
newText = ar.join('');
if (cursorPosition.start === query.length && query.endsWith('n')) {
this.props.input.onChange(newText)
} else if (this.state.allowEditing) {
this.props.input.onChange(newText)
this.setState({
selection: {
start: cursorPosition.start + 1,
end: cursorPosition.end + 1
},
allowEditing: !this.state.allowEditing
});
}
}}
multiline={true}
numberOfLines={3}
underlineColorAndroid='transparent'
blurOnSubmit={false}
returnKeyType='none'
style={combinedInputStyle}
/>
</View>
Can anyone see the issue?

Try console.dir(this.state); I suspect query isn't as you think.

Error and its place suggest you trying to do undefined.split('') - check your this.state.query, seems like it is not set:
onSelectionChange={(event) => this.setState({ cursorPosition: event.nativeEvent.selection, selection: event.nativeEvent.selection })}
