Use the plugin to copy the asset to a local path on the device:

import 'package:large_file_handler/large_file_handler.dart';

Future<void> copyAssetToLocal() async {
  String status;
  try {
    const assetName = 'example.json';
    const targetPath = 'example.json';

    await AssetCopy.copyAssetToLocalStorage(assetName, targetPath);
    status = 'File copied successfully to $targetPath';
  } on PlatformException catch (e) {
    status = 'Failed to copy asset: ${e.message}';
  }
}

  String status;
  try {
    const url = 'https://cloud/example.json';
