Convert intent web url to Android Intent

I currently integrate a webview (webview_flutter: 2.0.4) in my application for a payment process. Unfortunately, at some point the following url is launched:

intent://payment#Intent;action=ch.twint.action.TWINT_PAYMENT;scheme=twint;S.code=18223;S.startingOrigin=EXTERNAL_WEB_BROWSER;S.browser_fallback_url=;end

This URL should launch the "twint" application (Swiss payment solution) Unfortunately it doesn't work so I'm trying to recreate the corresponding android intent (android_intent: 2.0.0) but I can't.

Can anyone help me or any other idea for a solution?

I also tried with the url_launcher extension but I don't think it's the right solution.

I don't know if you can execute native kotlin/java code when using flutter, but this can be solved (natively) by using the following code (taken from https://stackoverflow.com/a/35612860):

override fun shouldOverrideUrlLoading(view: WebView?, url: String): Boolean {

        if (url.startsWith("intent://")) {
            val intent = Intent.parseUri(url, Intent.URI_INTENT_SCHEME);
            return if (intent.resolveActivity(context.packageManager) != null) {
                context.startActivity(intent)
                true
            } else {
                // handle error, e.g. open playstore
                true
            }
        }
        /* 
          Rest of override url handling
          ...
        */
    }

On Android API 30+ intent.resolveActivitywill only detect the installed twint app if you have the following entry in your AndroidManifest.xml:

<queries>
    <intent>
        <action android:name="ch.twint.action.TWINT_PAYMENT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="twint" />
    </intent>
</queries>
