Geolocation clearWatch(watchId) does not stop location tracking (React Native)

I'm trying to create simple example of location tracker and I'm stuck with following case. My basic goal is to toggle location watch by pressing start/end button. I'm doing separation of concerns by implementing custom react hook which is then used in App component:
useWatchLocation.js
import {useEffect, useRef, useState} from "react"
import {PermissionsAndroid} from "react-native"
import Geolocation from "react-native-geolocation-service"
const watchCurrentLocation = async (successCallback, errorCallback) => {
if (!(await PermissionsAndroid.check(PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION))) {
errorCallback("Permissions for location are not granted!")
}
return Geolocation.watchPosition(successCallback, errorCallback, {
timeout: 3000,
maximumAge: 500,
enableHighAccuracy: true,
distanceFilter: 0,
useSignificantChanges: false,
})
}
const stopWatchingLocation = (watchId) => {
Geolocation.clearWatch(watchId)
// Geolocation.stopObserving()
}
export default useWatchLocation = () => {
const [location, setLocation] = useState()
const [lastError, setLastError] = useState()
const [locationToggle, setLocationToggle] = useState(false)
const watchId = useRef(null)
const startLocationWatch = () => {
watchId.current = watchCurrentLocation(
(position) => {
setLocation(position)
},
(error) => {
setLastError(error)
}
)
}
const cancelLocationWatch = () => {
stopWatchingLocation(watchId.current)
setLocation(null)
setLastError(null)
}
const setLocationWatch = (flag) => {
setLocationToggle(flag)
}
// execution after render when locationToggle is changed
useEffect(() => {
if (locationToggle) {
startLocationWatch()
} else cancelLocationWatch()
return cancelLocationWatch()
}, [locationToggle])
// mount / unmount
useEffect(() => {
cancelLocationWatch()
}, [])
return { location, lastError, setLocationWatch }
}
App.js
import React from "react"
import {Button, Text, View} from "react-native"
import useWatchLocation from "./hooks/useWatchLocation"
export default App = () => {
const { location, lastError, setLocationWatch } = useWatchLocation()
return (
<View style={{ margin: 20 }}>
<View style={{ margin: 20, alignItems: "center" }}>
<Text>{location && `Time: ${new Date(location.timestamp).toLocaleTimeString()}`}</Text>
<Text>{location && `Latitude: ${location.coords.latitude}`}</Text>
<Text>{location && `Longitude: ${location.coords.longitude}`}</Text>
<Text>{lastError && `Error: ${lastError}`}</Text>
</View>
<View style={{ marginTop: 20, width: "100%", flexDirection: "row", justifyContent: "space-evenly" }}>
<Button onPress={() => {setLocationWatch(true)}} title="START" />
<Button onPress={() => {setLocationWatch(false)}} title="STOP" />
</View>
</View>
)
}
I have searched multiple examples which are online and code above should work. But the problem is when stop button is pressed location still keeps getting updated even though I invoke Geolocation.clearWatch(watchId).
I wrapped Geolocation calls to handle location permission and other possible debug stuff. It seems like watchId value that is saved using useRef hook inside useWatchLocation is invalid. My guess is based on attempting to call Geolocation.stopObserving() right after Geolocation.clearWatch(watchId). Subscription stops but I get warning:
Called stopObserving with existing subscriptions.
So I assume that original subscription was not cleared.
What am I missing/doing wrong?
EDIT: I figured out solution. But since isMounted pattern is generally considered antipattern: Does anyone have a better solution?
Ok, problem solved with isMounted pattern. isMounted.current is set at locationToggle effect to true and inside cancelLocationWatch to false:
const isMounted = useRef(null)
...
useEffect(() => {
if (locationToggle) {
isMounted.current = true // <--
startLocationWatch()
} else cancelLocationWatch()
return () => cancelLocationWatch()
}, [locationToggle])
...
const cancelLocationWatch = () => {
stopWatchingLocation(watchId.current)
setLocation(null)
setLastError(null)
isMounted.current = false // <--
}
And checked at mount / unmount effect, success and error callback:
const startLocationWatch = () => {
watchId.current = watchCurrentLocation(
(position) => {
if (isMounted.current) { // <--
setLocation(position)
}
},
(error) => {
if (isMounted.current) { // <--
setLastError(error)
}
}
)
}

losing my mind - why doesn't my fetch re render (redux)

In my project I have many users and many resources (and many user_resources/the join between users and resources).When I POST to user_resources I see it work on my rails backend (as in I see that instance posted) but in my react native front end I don't see it listed upon update. However, once the app is completely refresh (when I stop and restart the expo server), I finally see those items rendered. ANY IDEAS? I've been working on this forever now to no avail and my project is due tmrw, so any help is appreciated.
screen where I post to user_resources:
import React from 'react';
import { ScrollView,SafeAreaView,StyleSheet, Text, View, FlatList, TouchableOpacity,Button, NativeEventEmitter} from 'react-native';

state = {

this.props.fetchResources();
}
FlatListItemSeparator = () => {
return (

);
}
handlePress(item) {
debugger

},

.then(res => res.json())
.then(data2 => {

}
}
const mapDispatchToProps = (dispatch) => {
return {
fetchResources: () => dispatch(fetchResources()),
addUserResource,
searchChanged
}
}
export default connect(mapStateToProps,mapDispatchToProps)(ResourcesScreen)
After this I head to the profile page where the user_resources SHOULD be displayed, but aren't
import React from 'react';
import { ScrollView,StyleSheet, Text, View, FlatList, TouchableOpacity} from 'react-native';
import {connect} from 'react-redux';
import {SearchBar} from 'react-native-elements';
import { AntDesign } from '#expo/vector-icons';
class Profile extends React.Component{
handleDelete = (id) => {
debugger
fetch(`http://localhost:3000/user_resources/${id}`, {
method: "DELETE",
headers: {
"Authorization": this.props.users.token
}
})
.then(r => r.json())
.then((delResource) => {
console.log(delResource)
this.props.deleteOneFood(delResource)
console.log('deleted')
this.forceUpdate()
})
}
render(){
return(
<View>
{this.props.users.user_resources.map(singleResource=> {
return <Text key={singleResource.id}>{singleResource.name}</Text>
})}
</View>
)}
}
let deleteOneResource = (id) => {
return {
type: "DELETE_ONE_USER_RESOURCE",
payload: id
}
}
const mapDispatchToProps = {
deleteOneResource
}
const mapStateToProps = (state) => {
return {
users: state.userReducer,
}
}
export default connect(mapStateToProps,mapDispatchToProps)(Profile)
I had a flatlist before but thought that may be causing the issues so rendered it another way, still no luck. I tried forceUpdates as well, still no luck. I'm not sure if the issue is coming from my reducer:
let userInitialState = {
id: 0,
username: "",
name: '',
category: '',
token: "",
user_resources:[],
}
let userReducer = (state = userInitialState, action) => {
switch(action.type){
case "ADD_USERS":
let singleNestedObject = {
...action.users.user,
token: action.users.token
}
return {
...state,
username: action.users.user.username,
token: action.users.token,
id: action.users.user.id,
name: action.users.user.name,
category: action.users.user.category,
user_resources: action.users.user.user_resources
}
case "ADD_ONE_USER_RESOURCE":
let copyOfResources = [...state.user_resources, action.userResources]
return {
...state,
user_resources: copyOfResources
}
default:
return state
}
}
and it's action
export const addUserResource = (resourceInfo) => {
return {
type: "ADD_ONE_USER_RESOURCE",
userResources: resourceInfo
}
}
Please help me find the issue here, I'm losing it.

Lodash debounce not working all of a sudden?

I'm using a component I wrote for one app, in a newer app. The code is like 99% identical between the first app, which is working, and the second app. Everything is fine except that debounce is not activating in the new app. What am I doing wrong?
// #flow
import type { Location } from "../redux/reducers/locationReducer";
import * as React from "react";
import { Text, TextInput, View, TouchableOpacity } from "react-native";
import { Input } from "react-native-elements";
import { GoogleMapsApiKey } from "../../.secrets";
import _, { debounce } from "lodash";
import { connect } from "react-redux";
import { setCurrentRegion } from "../redux/actions/locationActions";
export class AutoFillMapSearch extends React.Component<Props, State> {
textInput: ?TextInput;
state: State = {
address: "",
addressPredictions: [],
showPredictions: false
};
async handleAddressChange() {
console.log("handleAddressChange");
const url = `https://maps.googleapis.com/maps/api/place/autocomplete/json?key=${GoogleMapsApiKey}&input=${this.state.address}`;
try {
const result = await fetch(url);
const json = await result.json();
if (json.error_message) throw Error(json.error_message);
this.setState({
addressPredictions: json.predictions,
showPredictions: true
});
// debugger;
} catch (err) {
console.warn(err);
}
}
onChangeText = async (address: string) => {
await this.setState({ address });
console.log("onChangeText");
debounce(this.handleAddressChange.bind(this), 800); // console.log(debounce) confirms that the function is importing correctly.
};
render() {
const predictions = this.state.addressPredictions.map(prediction => (
<TouchableOpacity
style={styles.prediction}
key={prediction.id}
onPress={() => {
this.props.beforeOnPress();
this.onPredictionSelect(prediction);
}}
>
<Text style={text.prediction}>{prediction.description}</Text>
</TouchableOpacity>
));
return (
<View>
<TextInput
ref={ref => (this.textInput = ref)}
onChangeText={this.onChangeText}
value={this.state.address}
style={[styles.input, this.props.style]}
placeholder={"Search"}
autoCorrect={false}
clearButtonMode={"while-editing"}
onBlur={() => {
this.setState({ showPredictions: false });
}}
/>
{this.state.showPredictions && (
<View style={styles.predictionsContainer}>{predictions}</View>
)}
</View>
);
}
}
export default connect(
null,
{ setCurrentRegion }
)(AutoFillMapSearch);
I noticed that the difference in the code was that the older app called handleAddressChange as a second argument to setState. Flow was complaining about this in the new app so I thought async/awaiting setState would work the same way.
So changing it to this works fine (with no flow complaints for some reason. maybe because I've since installed flow-typed lodash. God I love flow-typed!):
onChangeText = async (address: string) => {
this.setState(
{ address },
_.debounce(this.handleAddressChange.bind(this), 800)
);
};

React native - Can't dispatch action in component because state gets undefined

In my react native android app, when I try to dispatch an action in BoardsScreen or in the root of the app, the following error pops up:
However, when I remove it, the app doesn't crashes.

I really don't have a clue what is causing this, maybe it's a bug but I don't know if is react-redux fault or react native itself.
When you remove the board, it looks like in you reducer, you return a strange new state:
case 'REMOVE_BOARD':
newState = {
boards: action.payload,
};
return newState;
Should the boards to be an array always? I think you missed something, for example:
boards: state.boards.filter ((it) => it.id !== action.payload.id),
