Unresolved reference: viewmodel compose 省略viewModel

添加依赖

def lifecycle_version = "2.5.1"

    implementation "androidx.lifecycle:lifecycle-runtime-ktx:$lifecycle_version"
    implementation "androidx.lifecycle:lifecycle-viewmodel-compose:$lifecycle_version"

偷懒后

@Composable
fun MainScreen(mainViewModel: MainViewModel = viewmodel()) {
}
