Cannot find declaration of: remember { ... }

Workaround: add to imports import androidx.compose.runtime.getValue import androidx.compose.runtime.setValue

Did you try to sync the project with Gradle?

Also can you provide archive with the project and tell what version of IDEA/Kotlin plugin are you using?

[atoktoto]

I've tried to:

• sync as instructed
• upgraded to latest compose (0.1.0-build119)
• invalidate & restart

The project: https://github.com/atoktoto/compose-experiment (based on a provided desktop template)

Thanks! Reproduced the issue

The same thing happens in Android studio and iirc it's intentional since it's an intrinsic.

The thing is, it makes it hard to understand what is going on without prior experience in Android dev. I finally found the documentation: https://developer.android.com/reference/kotlin/androidx/compose/runtime/package-summary#remember https://developer.android.com/jetpack/compose/state

It also has a kotlin implementation in source code: https://cs.android.com/androidx/platform/frameworks/support/+/androidx-master-dev:compose/runtime/runtime/src/commonMain/kotlin/androidx/compose/runtime/Remember.kt?q=remember&ss=androidx%2Fplatform%2Fframeworks%2Fsupport:compose%2Fruntime%2Fruntime%2F

I have the same error. Some more information:

and

Treated with replacement import androidx.compose.runtime.remember to import androidx.compose.runtime.*

Compose v. 0.2.0-build131 and earlier

Construction val a = remember { .... } works fine...

[igordmn]

Error "has no method" happened because there are no these imports in the file:

import androidx.compose.runtime.getValue
import androidx.compose.runtime.setValue

getValue/setValue are kotlin delegates needed for "var test by" expression.

IDEA doesn't offer to import them if we wrap mutableStateOf in remember, so we have to write them manually.
