feat: ability to open more than 1 webview and post messages to all or only specific one

[Albermonte]

Feature Request

Description

Right now if you open one webview on top of other it will overwrite the current one, resulting in not being able to communicate with more than 1 webview and when closing the last open webwiew the communication with the other webview wont be recovered.

I want to be able to open as many webviews as I want and being able to communicate with all of them in a broadcast like way or only with a specific one.

Platform(s)

iOS, Android

Preferred Solution

What I'm currently doing is assigning a random uuid to every new webview I open and returning that uuid with the openWebView method. If I want to broadcast a message to all the webviews I will just use postMessage without any id, but if I want to communicate with a specific webview I would do:

await InAppBrowser.postMessage({
  webViewId: uuid,
  detail: { message: 'Hello WebView!' }
});

Hi, this is a discussion we had internally not long-ago. We don't currently plan to add a feature like this, but we will keep in mind that there is interest in this feature.

[Albermonte]

Would you be open for a PR with this feature (at least with the basics I need) that doesn't affect the current use of the plugin?

[WcaleNieWolny]

Sure, I would be open for that
