InvalidValueError if using findAutocompletePredictions with origin

[acheronian]

Heyo :)

When attempting to use the findAutocompletePredictions method from the flutter_google_places_sdk_web package, an InvalidValueError is thrown. The error message indicates that the origin property is not a valid LatLng or LatLngLiteral object because the lat property is not a number.

Curiously, the issue only occurs sporadically. Sometimes, everything works, sometimes not. Maybe it has something to do with multiple packages using the same google maps javascript skd?

Steps to Reproduce

1. Call findAutocompletePredictions with an origin parameter that is expected to be a valid LatLng object.
2. Observe that the error is thrown indicating that the lat property within the origin is not a number.

Expected Behavior

The findAutocompletePredictions method should accept a valid LatLng object without throwing an error.

Actual Behavior

An InvalidValueError is thrown, indicating that the lat property of the origin parameter is not a number.

@acheronian I tried running it multiple times in a row - I don't seem to get that or any error, never.

The web implementation uses the JS web service provided by google JS api, and just provides LatLng to it - I can't think of any reason it would be different suddenly Ref: https://developers.google.com/maps/documentation/javascript/reference/places-autocomplete-service#AutocompletionRequest.origin

Any chance you're passing null to it from time to time, depending on how you use it?

If not, can you create a reproducible example or steps to be used with the example project?

@matanshukry I've managed to resolve the issue by following the instructions provided in https://github.com/matanshukry/flutter_google_places_sdk/issues/16. It appears there was a specific edge case coupled with google_maps_flutter package that wasn't handled properly in our implementation, which has now been addressed.

Thank you for pointing me in the right direction!
