Can't call setState (or forceUpdate) on an unmounted component.

Error:

Can't call setState (or forceUpdate) on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in the componentWillUnmount method.

Description:

Pressing on a “Place” item in the listview from react-native-google-places-autocomplete triggers the error. I’ve stepped through it in Chrome’s devtools and found the error occurs right after TouchableHighlight from _renderRow (please see screenshot below).

Code:

  <GooglePlacesAutocomplete
    autoFocus
    debounce={200}
    enablePoweredByContainer={false}
    fetchDetails={false}
    GooglePlacesSearchQuery={{
      rankby: 'distance',
      types: 'establishment'
    }}
    listViewDisplayed={destinationInput}
    minLength={2}
    nearByPlacesAPI="GooglePlacesSearch"
    onPress={data => setDestination(data)}
    placeholder="Where to?"
    placeholderTextColor="black"
    ref={setRef}
    returnKeyType="search"
    styles={searchDestStyle}
    textInputProps={{
      onBlur: blurDest,
      onFocus: focusDest
    }}
    query={{
      key: config.apiKey,
      language: 'en',
      types: ['establishment', 'geocode'],
      location: '37.786279,-122.406456',
      radius: '15000',
      components: 'country:us'
    }}
  />

destinationInput is a Boolean from redux state. setDestination, blurDest, focusDest are a redux action creators. setDestination sends the location data to redux state, which react-native-maps-directions uses to send direction coordinates to react-native-maps. Then a react-native modal is triggered.

I have the same problem and setting debounce to 0 didn’t help. The warning is still there half of the times.

set debounce to 0 if it is fine with your usecase.
