Hi. I just need more details. What javascript code are you trying to evaluate?

Hi. I just need more details. What javascript code are you trying to evaluate?

when I compile to Android apk and run, click more than 5 times, will be crash, everytime.
code like this:

    class _HomeState extends State<Home> {
      JavascriptRuntime rt;
    
      @override
      void initState() {
        super.initState();
        rt = getJavascriptRuntime();
      }
    
      @override
      Widget build(BuildContext context) {
        return Container(
          child: GestureDetector(
            child: Text('run js'),
            onTap: () {
              JsEvalResult result = rt.evaluate('1+1;');
              print('result:$result');
            },
          ),
        );
      }
    }

and log is :

there is no problem when code like this:

    onTap: () {
      JsEvalResult result = getJavascriptRuntime().evaluate('1+1;');
      print('result:$result');
    },

I want reuse JavascriptRuntime.

seem like the log of flutter using print('1) when on tap, the output log aways same, then flutter's log will not output!
