如何将价值从 android-project 发送到 share-project？

Question

如何将verificationId从SendOtpCodeAsync()发送到SendCode_Button_Clicked()

分享项目代码

 IAuth auth; 
 auth = DependencyService.Get<IAuth>();
private async void SendCode_Button_Clicked(object sender, EventArgs e)
{
       bool result = await auth.SendOtpCodeAsync(PhonenumberEntry.Text);
}

android项目代码

[assembly: Dependency(typeof(AuthDriod))]
namespace TestApp_MiniApps.Droid
{
    public class AuthDriod : PhoneAuthProvider.OnVerificationStateChangedCallbacks, IAuth
    {
        private TaskCompletionSource<bool> _phoneAuthTcs;

        public Task<bool> SendOtpCodeAsync(string phonenumber)
        {
            _phoneAuthTcs = new TaskCompletionSource<bool>();

            Java.Lang.Long num = (Java.Lang.Long)60;
            PhoneAuthOptions options =
                PhoneAuthOptions.NewBuilder(FirebaseAuth.Instance)
                .SetPhoneNumber(phonenumber)       // Phone number to verify
                .SetTimeout(num, TimeUnit.Seconds) // Timeout and unit
                .SetActivity(Platform.CurrentActivity)                 // Activity (for callback binding)
                .SetCallbacks(this)          // OnVerificationStateChangedCallbacks
                .Build();
            PhoneAuthProvider.VerifyPhoneNumber(options);

            return _phoneAuthTcs.Task;
        }

        public override void OnVerificationCompleted(PhoneAuthCredential credential)
        {      
        }

        public override void OnVerificationFailed(FirebaseException exception)
        {
            _phoneAuthTcs?.TrySetResult(false);
        }

        public override void OnCodeSent(string verificationId, PhoneAuthProvider.ForceResendingToken forceResendingToken)
        {
            base.OnCodeSent(verificationId, forceResendingToken);
            _phoneAuthTcs?.TrySetResult(true);

        }
    }//end of class
}

要总结 Leo 在 cmets 中添加的内容，您可以检查方法调用返回的内容。

从bool 更改为您自己的班级。出于此答案的目的，我将其称为OtpResult。

// The new class definition:
public class OtpResult
{
    public bool Success { get; set; }

    // Define whatever you like here
    public string StringValue { get; set; }
}


public interface IAuth
{
    Task<OtpResult> SendOtpCodeAsync(string phonenumber);
}
