huawei location package throwing error while build web

[alamen-pgooja]

Description I'm using the same codebase for mobile and web, and I use the Huawei location library. When I run flutter build web, the build crashes during the compilation of the library. Log:

Target dart2js failed: ProcessException: Process exited abnormally with exit code 1:
../../.pub-cache/hosted/pub.dev/huawei_location-6.12.0+302/lib/src/location/location_request.dart:120:23:
Error: The integer literal 9223372036854775807 can't be represented exactly in JavaScript.
    _expirationTime = 9223372036854775807;

Expected Behavior The build should compile normally.

Current Behavior The build fails during compilation.

Huawei Flutter Location Library depend on Huawei Android Location SDK, it is intended to be used with Android only and it is not compatible with web applications, as a workaround, consider using conditional import to exclude Huawei Location library from your web build:

this code was not tested

create empty implementation for Web platform

example path: lib/stubs/huawei_location_stub.dart:

class FusedLocationProviderClient {
  // Define the methods and properties used from Huawei Location library.

  Future<void> getLastLocation() async {
    // No implementation for web.
  }
  // Add other methods as needed.
}

use conditional import to exclude real FusedLocationProviderClient for web

example path: lib/location_service_selector.dart:

export 'package:huawei_location/huawei_location.dart'
    if (dart.library.html) 'stubs/huawei_location_stub.dart';

update your code to import from location service selector

import 'package:flutter/material.dart';
import 'location_service_selector.dart';

class LocationScreen extends StatelessWidget {
  LocationScreen({Key? key}) : super(key: key);

  final FusedLocationProviderClient _locationService =
      FusedLocationProviderClient();

  getLastLocation() async {
    final Location location = await _locationService.getLastLocation();
    // ...
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(...);
  }
}
