问题 I'm building an app which will scrape some data from a website and shows a notification when some criteria are met. Everything works well without problems when the app is open (because the WebView is being rendered) but when I close the app the WebView is disabled so I cannot use it to scrape data anymore. The scraping code is inside a class called from a ForegroundService. I've already looked on the internet but I'm unable to find a solution or a substitute to WebView, do you have any ideas?

问题 I am using flutter_webview_plugin: ^0.3.8 but I have the same problem with webview_flutter: ^0.3.13 .

问题 I want to snapshot the WebView after the WebView is loaded. However, the returned bitmap is always null because the render hasn't loaded completed even though I use onPageFinished .
