The iOS and Android execution returns are inconsistent

flutter version: 3.7.7
flutter_webview_plugin version: 0.4.0

my code：
```
final flutterWebviewPlugin = FlutterWebviewPlugin();
var js = "var jsonRes = {\"abc\": 1, \"array1\": [1, 2, 3]};jsonRes";
await flutterWebviewPlugin.launch("about:blank", withJavascript: true, hidden: true);
String? javascriptResult = await flutterWebviewPlugin.evalJavascript(js) ?? '';
```
Android returned the correct result
iOS result：{
abc = 1;
array1 = (
1,
2,
3
);
}

What's going on here? Can you help me, please

The issue names no source files or tests. Start by reproducing the evalJavascript snippet on both Android and iOS with the stated Flutter and plugin versions, then trace the platform-specific JavaScript evaluation paths. Done means the same structured result is returned on both platforms, or the platform difference is documented and explained.
