Flutter_How to scrap the data from Javascript in web?

I need to get data from javascript in web-site.

It was successful to get data from general html web by using flutter_webscrapper dart package but looks lik开发者_如何学JAVAe the webscrapper do not support to load javascript and scrap it.

I've been searching it and lots of developers recommend to use flutter_webview as headless browser. However, flutter_webview spends too much time to create browser & load website. It takes almost over 4~5 seconds. Seems that challenge to use it in commercial product.

I also cannot use flutter_puppeteer because it does not support android & ios.

If there are any other way or other Dart package to scrap the data from javascript in web-site, please let me recommend. Waiting for your supports.
