Flutter Dart: RegEx to extract URLs from a String

Question

This is my string:

    window.urlVideo = 'https://node34.vidstreamcdn.com/hls/5d59908aea5aa101a054dec2a1cd3aff/5d59908aea5aa101a054dec2a1cd3aff.playlist.m3u8';
var playerInstance = jwplayer("myVideo");
var countplayer = 1;
var countcheck = 0;
playerInstance.setup({
    sources: [{
        "file": urlVideo
    }],
    tracks: [{
        file: "https://cache.cdnfile.info/images/13f9ddcaf2d83d846056ec44b0f1366d/12.vtt",
        kind: "thumbnails"
    }],
    image: "https://cache.cdnfile.info/images/13f9ddcaf2d83d846056ec44b0f1366d/12_cover.jpg",
});

function changeLink() {
    window.location = "//vidstreaming.io/load.php?id=MTM0OTgz&title=Mairimashita%21+Iruma-kun+Episode+12";
}
window.shouldChangeLink = function () {
    window.location = "//vidstreaming.io/load.php?id=MTM0OTgz&title=Mairimashita%21+Iruma-kun+Episode+12";
}

I am using flutter dart.

How can I get window.urlVideo URL link and image URL link and .vtt file link?

Or

How can I get a list of URLs from a String? I tried finding a way with and without using RegEx but I couldn't.

Any help is apreciated

Getting just the https? and ftp url's that are in quotes is this :

r"([\"'])\s*((?:(?:https?|ftp):\/\/)(?:\S+(?::\S*)?@)?(?:(?:(?:[1-9]\d?|1\d\d|2[01]\d|22[0-3])(?:\.(?:1?\d{1,2}|2[0-4]\d|25[0-5])){2}(?:\.(?:[1-9]\d?|1\d\d|2[0-4]\d|25[0-4]))|(?:(?:[a-zA-Z0-9\u00a1-\uffff]+-?)*[a-zA-Z0-9\u00a1-\uffff]+)(?:\.(?:[a-zA-Z0-9\u00a1-\uffff]+-?)*[a-zA-Z0-9\u00a1-\uffff]+)*(?:\.(?:[a-zA-Z\u00a1-\uffff]{2,})))|localhost)(?::\d{2,5})?(?:\/(?:(?!\1|\s)[\S\s])*)?)\s*\1"

Where the Url is captured in group 2.
