projectman | command line tool to easily save | Command Line Interface library

Im trying to figure out how to do something with my dart project and I am not really sure where to start. To preface this, Dart is the first language that I am learning fully. I have put over 100 hours into training and building this project over the past few months. This is also my first major project in the language, and I really am loving what I have been able to come up with.

Here is the layout of one of my Project Board pages. This is the Dashboard page. On my web app, I am receiving data from a Mongo Db using mongo_dart on a dart server. I am then taking the data and serializing it into what I believe is a List. I am creating a card for each project that includes some basic information about the project (That info is from the database). Oh this card I want to include all of the "project tasks" (that I put into material-chips using ngFor), but there will be upwards of 10+ tasks per project, which takes up a lot of room on the page. So to save space, I would like for the card to show only 3 tasks at a time, then rotate to the next 3 after a few seconds, and so on. So each card will have 3 chips, then the chips will change to the next 3, etc. The goal is to make a page that someone can glimpse at and quickly see the open projects and the tasks/who the task is assigned to and what the status is. being able to see 5-10 project cards on a page is ideal. I believe I can use Angular Animations to hide/remove portions of my map, then set up a timer for the transition to reveal the next , but again I have no idea how to start this.

I am posting the HTML below but I am more than happy to post any more info that you may need. I am running Dart Version 2. Also, I know my code is not the prettiest. I am still learning so any input on improvements I can make will be super helpful! Also if anyone has any advice on how to reuse portions of my html instead of having it copied 5 times (because of ngIf), I am open to hearing it!
