How to automatically fill a form on the loaded page?

Hi,
I want to be able to automatically fill a form on the page I am loading, with values from my application.

Is there a way to do this? perhaps injecting some JS code in the page, or having access to the page's DOM after it loads...

Any ideas will be appreciated.

首先阅读插件现有的 Flutter-to-native WebView 通信入口点，并检查是否已经提供页面 JavaScript 或 DOM 访问能力。确定所请求的表单填充需要 JavaScript 注入、DOM 访问，还是两者都需要，然后在已加载的页面上验证所选方案，并记录受支持的行为。
