Question

I was trying to make this example from youtube but I have 2 problems The first one is that state is deprecated but I cant make remember work with these 2 values The second thing is that I cannot ripple anymore from Modifier Code ``` Composable fun ModifiedShape TODO Replace by remember val shape setShape = state CircleShape TODO Fix error Destructuring declaration initializer of type Shape must have a component1 function Destructuring declaration initializer of type Shape must have a component2 function val shape setShape = remember CircleShape Image asset = imageResource id = R drawable ic launcher background modifier = Modifier size 256 dp padding 16 dp drawShadow 8 dp shape border 6 dp MaterialTheme colors primary shape border 12 dp MaterialTheme colors secondary shape border 18 dp MaterialTheme colors background shape TODO Add ripple ripple color = MaterialTheme colors surface clickable setShape if shape == CircleShape CutCornerShape topLeft = 32 dp bottomRight = 32 dp else CircleShape ```

Replace `= state` with = `= remember mutableStateOf CircleShape `

Yann Badoual · Answer

The `clickable` modifier should apply a ripple by default I believe It can be changed with the `interaction` parameter of `clickable` modifier As for the color I m not sure what color it s using by default But you can create your own instance of `RippleIndication` and pass the color you want if needed You can check the default value in `DefaultRippleTheme ` By default it seems to be either white or `contentColor ` depending on current theme light or dark and contentColor s lumiance

I tried to edit remember but getting these two errors

Geert · Answer

There is something wrong with the Shape type I guess

Brett Best · Answer

< Geert> try two expressions

Brett Best · Answer

Might also need to instantiate the CircleShape

Brett Best · Answer

`mutableStateOf CircleShape `

Geert · Answer

Instantiate is not working Also setshape is not working anymore

Brett Best · Answer

Do you have this on GitHub

Geert · Answer

No I just created a new project and this is the only code

Geert · Answer

This is the video but thery are using an old version if Compose i guess <https youtu be U5BwfqBpiWU t=609>

Geert · Answer

This line is actually working ```val shape setShape = remember mutableStateOf CircleShape ``` But the CutCornerShape and CircleShape are both inheriting the Shape interface

Geert · Answer

But the problem with the shape interface is that is doesnt have the destructering declaration

Geert · Answer

And I cannot use mutableState of Shape since its an interface

Yann Badoual · Answer

```val shape setShape = remember mutableStateOf lt Shape gt CutCornerShape ```

Yann Badoual · Answer

this should work the type parameter should be specified on `mutableStateOf` and the argument should be the default value

Yann Badoual · Answer

so you need to pass an actual instance and not a type Shape

Geert · Answer

Yes thank you I see that remember must be MutableState So that was why I couldn t specify Shape I did it in the wrong place

Geert · Answer

And CutCornershape has to be instantiated but with more parameters but using CircleShipe only it also works

Geert · Answer

Where CircleShape is instantiated already ```val CircleShape = RoundedCornerShape 50 ```

Yann Badoual · Answer

Btw you can also use the following form `var shape by remember mutableStateOf CirlceShape ` and instead of calling `setShape` you can use `shape` as a mutable variable If you do just make sure to add the following import ```import androidx compose runtime getValue import androidx compose runtime setValue``` Or you ll get an error known intellij bug
