Type `int` is not a subtype of type `String?` in type cast

This happens when we're running a flutter app on iOS with cx_flutter_plugin. It looks like response_content_length is being sent as a String from Android native side while on iOS, it is being sent as an int while trying to parse NetworkRequestContext.

We forked the package and are using the following hot-fix in the meantime, though it should probably be fixed on the platform channel level.

 factory NetworkRequestContext.fromJson(Map<String, dynamic> json) {
    return NetworkRequestContext(
      method: json['method'] as String,
      statusCode:
          json['status_code'] is String ? int.tryParse(json['status_code'] as String) ?? 0 : json['status_code'] as int,
      url: json['url'] as String,
      fragments: json['fragments'] as String?,
      host: json['host'] as String?,
      schema: json['schema'] as String?,
      statusText: json['status_text'] as String?,
-     responseContentLength: json['response_content_length'] as String?,
+     responseContentLength: switch (json['response_content_length']) {
+       String s => s,
+       int i => i.toString(),
+       null => null,
+         _ => '0'
+     },
      duration:
          json['duration'] is String ? int.tryParse(json['duration'] as String) ?? 0 : json['duration'] as int? ?? 0,
    );
  }
