All language subtitles for 11. Challenge 1 Solution

All right.
1

So how did you get on with that challenge?
2

This should be quite simple because we've already done it once for the left dice. But it's important
3

that you understand how it all links together, which is why I wanted you to complete the challenge.
4

The first thing that we need to do is we've got a variable that's tracking the value for our leftDice
5

Number. And it's updating it when the button is pressed. So that it can display a new image in that image
6

widget.
7

Now in order to do the same for the right dice, we're going to need to create a new variable. And we'll
8

just call this rightDice
9

Number, because not feeling too imaginative today.
10

Now once we've got our variable, then we can go about changing it to a random number, when the flap button
11

is pressed. Inside our onPressed,
12

the first thing we're gonna do is we're going to say that our rightDiceNumber is going to equal to
13

a number that's generated from a random number generator.
14

And the specific type of number we want to generate is an integer,
15

so a whole number. And we're going to set the max to six.
16

So we generate random numbers between 0 and 5. And then we'll just add 1 to any of those numbers to bring
17

it up to 1 - 6, which matches with the dice numbers that we have in our images.
18

The next thing we're going to do is we're going to update the place where we use that rightDiceNumber.
19

Instead of pulling up the images/dice1.png, which is pretty much hardcoded, it's always going
20

to be the first image shown. We're going to delete that one, and instead we're going to use a string interpolation
21

to insert the rightDiceNumber inside there. And it's going to be inserted using that little dollar
22

sign there that we saw previously.
23

Now all we have to do is to say that when the rightDiceNumber changes, we should update all the places
24

where it's used.
25

So in order to do that, we have to call that method called set state.
26

And this simply says that this change in the rightDiceNumber's value is going to need to trigger a
27

rebuild of our stateful widget, so that the part where it's used can update on the screen.
28

Let's hit save and for those changes to go through to our app, and let's test it by... we already know the
29

left side works.
30

And now if we click on the right side, it also works. And it gives us all the numbers that we could possibly
31

want.
32

And we now have two separate dice that we can roll on our dice app.
33

Now what if we wanted both dice to change when one of the buttons is pressed?
34

So what if I wanted both of these buttons to update when I click on any one of those buttons?
35

Here is your challenge.
36

Try and get this behavior in your app. So pause the video and try to complete this challenge.
37

And I'll share with you the solution in the next lesson.
