Flutter - 如何在 GetX 中广播？

Question

I have a requirement: I have A, B, C, D, E.... multi pages in App. And now When I click a button in Page E, change the keyword, All page's controller will get this notification and use this changed keyword to query the web server then update page's UI.

I know 'EventBus' can achieve this goal. Do you know how to do in GetX.

Answer 1

You can use Obx() widget. Then you can use FutureBuilder inside it for webserver requests.
