1
00:00:02,150 --> 00:00:05,300
So now that we know how to navigate around in our application,

2
00:00:05,300 --> 00:00:11,270
an important building block has been covered because you'll need navigation in basically any mobile

3
00:00:11,270 --> 00:00:12,740
app you're about to build.

4
00:00:12,740 --> 00:00:19,280
What you'll also need in most mobile apps you're building is a state management solution and here, we'll

5
00:00:19,280 --> 00:00:24,600
use Redux for that which is a popular state management solution for React.

6
00:00:24,710 --> 00:00:31,290
Now state management simply means that we need to manage the data our app relies on,

7
00:00:31,370 --> 00:00:37,130
like for example in the app we built in the navigation module where we had meals, where we could mark

8
00:00:37,130 --> 00:00:44,390
meals as a favorite and set filters, where we have data that we set in one area of our application and

9
00:00:44,390 --> 00:00:51,710
we need it in another area too and getting that data around effectively and updating Part B of our app

10
00:00:51,770 --> 00:00:53,620
if Part A changes,

11
00:00:53,750 --> 00:00:55,820
that's what state management is about.

12
00:00:55,850 --> 00:01:01,190
That's what's currently missing in this app we built in the last module and that's what we'll tackle

13
00:01:01,190 --> 00:01:02,140
in this module.
