Dynamic loading of external scripts

[SamuelUlep]

As far as I know this plugin allows the usage of javascript code in flutter, does this also allow during the runtime of the app to load external scripts from third parties?

I've experimented with this a bit. You will have to manage fetching third-party scripts yourself. I was only able to get UMD (Universal Module Definition) ES2023 scripts to work with QuickJS. If your third-party script uses other dependencies it may not work.

I was able to get UMD version of fuse.js work but you need to wrap the UMD module like below:

var window = {};
var document = {};
var module = { exports: {} };
var exports = module.exports;
var define = function (deps, factory) {
  if (typeof deps === "function") {
    module.exports = deps();
  } else {
    module.exports = factory();
  }
  define.amd = {};
};
var globalThis = typeof globalThis !== "undefined" ? globalThis : {};
var global = globalThis;
var self = globalThis;

// ***ADD YOUR UMD MODULE HERE***

typeof globalThis !== 'undefined' ? globalThis : global || self, global.ExampleDependency = module.exports;

ExampleDependency = global.ExampleDependency;

//Then you can use it like ExampleDependency.somepropertyOrFunction

It seems like I may be out of my depth here, I was looking for ways to dynamically load external scripts during runtime of a flutter app. I appreciate the help though.
