Notes from "What I learned"
- js export doesn't work, use
(<any>window).functionNameto register js functions - Putting HTML element inside Flutter Web Widget is possible using
HtmlElementView(but expensive)

- Call methods and variables from JavaScript file (by channeling) using
js.context.callMethod('functionName, args') - Weird
platformViewRegistryerror but solved by ignoring

- Conditional export/import on dart
