re: How to use JavaScript libraries in your Dart applications VIEW POST


Sorry, not sure I follow what you mean here. Could you expand on this?

Let's say I want to use the moments.js library in my flutter application. Since it's already written, could I include this in my Flutter application and then call the functions in the moments library, or does it only work for interacting with the JS Window object?

Ahhh, thanks for clarifying. Only works with packages that are accessible via the window object, which will cover most browser-based JS packages. This is by design.

Out of interest, do you have a particular use case that warrants using a JS package in Flutter?

well there was an IMEI/credit card validator that was written in JS that I needed in one of my apps. I ended up converting it to dart code and then used it, but it would have been nice if I didn't need to. JS is so mature already I don't want to reinvent wheels I don't need to.

Oh right, got you. I tried a quick search on Pub that brought me across these two:

Haven't tried it myself, but would those have worked for your use case?

Awesome Jonathan! I'm glad you contributed in this way. I count this a victory. This also has the added benefit of not needing any JS interop, which helps with performance. Now I know where to look should I need credit card validation ;)
