我可以有
val composeFunction = remember { mutableStateOf ({}) }
我可以有
val composeFF = @Composable { Text("ABC") }
val composeFunction = remember { mutableStateOf (composeFF) }
為什么我不能
val composeFunction = remember { mutableStateOf (@Composable { Text("ABC") }) }
它出錯了狀態
Internal Error occurred while analyzing this expression
(Please use the "

Type inference failed. Expected type mismatch: inferred type is @Composable () -> Unit but () -> Unit was expected
uj5u.com熱心網友回復：
您是否嘗試過指定型別？
val composeFunction = remember { mutableStateOf<@Composable () -> Unit> (@Composable { Text("ABC") }) }
看起來編譯器無法將普通函式推斷為帶有@Composable注釋的東西
