Firebase anonymous sign in returns a task (which is basically Google promise implementation):
val task:Task<AuthResult> = FirebaseAuth.getInstance().signInAnonymously()
How it would be possible create a signInAnonymous wrapper where:
这是一个suspend函数，等待task完成
它返回一个Deferred对象，异步传递结果
fun signInAnonymous() : DeferredThe package kotlinx.coroutines.tasks now includes the follwing utility functions:
public suspend fun <T> Task<T>.await(): T { ... }
From the docs:
等待任务完成而不阻塞线程
public fun <T> Task<T>.asDeferred(): Deferred<T> { ... }
From the docs:
Converts this task to an instance of Deferred.
If task is cancelled then resulting deferred will be cancelled as well.
So you can just do:
suspend fun signInAnonymouslyAwait(): AuthResult {
return FirebaseAuth.getInstance().signInAnonymously().await()
}
or:
fun signInAnonymouslyDeferred(): Deferred<AuthResult> {
return FirebaseAuth.getInstance().signInAnonymously().asDeferred()
}
