I am trying with following code:

    let addresses = [];
    new google.maps.places.AutocompleteService().getPlacePredictions({
      input: addressQuery,
      componentRestrictions: {},
      // bounds: defaultBounds
    }, (predictions) => {
      console.log(predictions);
      addresses = predictions;
      return addresses;
    })

@SumeetHindinkeri can you share your full provider code?

[SumeetHindinkeri]

@jrquick17 The code that I posted above was actually my provider code with getResults function like below:

export class MapService implements AutoCompleteService {

public getResults(addressQuery) {
let addresses = [];
new google.maps.places.AutocompleteService().getPlacePredictions({
input: addressQuery
// bounds: defaultBounds
}, (predictions) => {
console.log(predictions);
addresses = predictions;
return addresses;
})
}
}

And html code:

<ion-auto-complete *ngIf='isEditable' [dataProvider]='mapService' (itemSelected)='onAddressInput($event)'
(ngModelChange)='clearInput()' [options]='{ placeholder : lAddressPlaceholder, debounce : "1000", clearIcon:"null"}'
[autoFocusSuggestion]='false' [(ngModel)]='address'>

Though I moved to different plugin afterwards.
