android - 指定为非 null 的参数 pendingDynamicLinkData 为 null

Question

private fun getReferralId() {
    Firebase.dynamicLinks
        .getDynamicLink(intent)
        .addOnSuccessListener(this) { pendingDynamicLinkData ->
            pendingDynamicLinkData?.link?.getQueryParameter(
                DEEP_LINK_QUERY_PARAM_REFERRAL_ID
            )?.let { refId ->
                viewModel.saveReferralId(refId)
            }
        }
}

java.lang.NullPointerException: Parameter specified as non-null isnull: method kotlin.jvm.internal.Intrinsics.checkNotNullParameter,parameter pendingDynamicLinkDataat app.package.activity.MainActivity.getReferralId$lambda-2(UnknownSource:7)at app.package.activity.MainActivity.$r8$lambda$ANLS0uCuXrQe7RFQ5b0C-RFsBKE(UnknownSource:0)at app.package.activity.MainActivity$$ExternalSyntheticLambda3.onSuccess(UnknownSource:4)

版本:

implementation platform("com.google.firebase:firebase-bom:28.3.1")
implementation "com.google.firebase:firebase-dynamic-links-ktx"

这里有什么问题？
更新
当我更新 play-services-auth 库的版本时会发生这种情况

implementation "com.google.android.gms:play-services-auth:19.2.0"
implementation "com.google.android.gms:play-services-auth-api-phone:17.5.1"

到最新版本

implementation "com.google.android.gms:play-services-auth:20.0.0"
implementation "com.google.android.gms:play-services-auth-api-phone:18.0.0"

这有什么关系？

这是一个 bug in the library由于播放服务更新。要修复它，您应该明确声明 pendingDynamicLinkData可以为空。
像这样:

private fun getReferralId() {
    Firebase.dynamicLinks
        .getDynamicLink(intent)
        .addOnSuccessListener(this) { pendingDynamicLinkData: PendingDynamicLinkData? ->
            pendingDynamicLinkData?.link?.getQueryParameter(
                DEEP_LINK_QUERY_PARAM_REFERRAL_ID
            )?.let { refId ->
                viewModel.saveReferralId(refId)
            }
        }
 }
