# Week 4

> Rocket.new December week 4 update: Visual Edit for Flutter, API imports, screenshot capture, custom code injection, and language defaults.

**December 24**

New

* **Visual Edit for Flutter**: Click any element in the mobile preview to modify it. No more describing every change in chat. [Learn more](https://dhiwisepvtltd-5e04e6a4.mintlify.site/build/editor/visual-edit.md)
* **API integrations**: Import from Postman, cURL, or Swagger and Rocket wires the endpoints into your UI automatically. [Learn more](https://dhiwisepvtltd-5e04e6a4.mintlify.site/build/editor/apis.md)

**December 23**

New

* **Screenshot capture**: Grab the preview and drag it into chat. Show Rocket what you want to change instead of describing it. [Learn more](https://dhiwisepvtltd-5e04e6a4.mintlify.site/build/editor/preview.md#capture-screenshots)
* **Inject custom code**: Add tracking scripts, widgets, fonts, or embeds through chat without touching the codebase. [Learn more](https://dhiwisepvtltd-5e04e6a4.mintlify.site/build/editor/custom-code.md)

**December 22**

Improved

* **React and Next.js language defaults**: React now uses JavaScript, Next.js now uses TypeScript. Existing projects in the non-default language continue to work.
