Here is the appdelegate setup --
import UIKit
import Flutter
import GoogleMaps
@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
GMSServices.provideAPIKey("abcdefghu123345") // <-- i have real key in my code
GeneratedPluginRegistrant.register(with: self)
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
}
Here is the error logs from Android Studio --
[VERBOSE-2:ui_dart_state.cc(209)] Unhandled Exception: NoSuchMethodError: The method 'call' was called on null.
Receiver: null
Tried calling: call()
#0 Object.noSuchMethod (dart:core-patch/object_patch.dart:38:5)
#1 _PhoneNumberInput.sendSMS (package:juggy/screens/phoneNumberInput.dart:72:34)
<asynchronous suspension>
Lost connection to device.
Code Snippet --
sendSMS() async{
var data = convert.json.encode({
'number': "+1$phoneNumber",
});
var requestHeaders = {
'Content-type': 'application/json',
'Accept': 'application/json',
};
var url = Uri.parse(
'https://us-central1-sonic-strains.cloudfunctions.net/app/api/twilioVerifyandSendCode');
// Await the http get response, then decode the json-formatted response.
// we need to verify code via sms
// so just change the ui back if bad request
var response = await http.post(url, body: data, headers: requestHeaders);
if (response.statusCode == 200) {
print("");
print("");
print("");
print("");
print("Calling toggle pin field");
await widget.togglePinField();
print("Calling toggle map field");
return widget.toggleMapField();
} else {
print('Request failed with status: ${response.statusCode}.');
print("");
print("your error for the sendSMS");
print(response);
// show the error & change the ui back if bad request
}
}
Just to recap
-
The app on IOS does not load the map but on web , android, etc the map loads fine.
-
The function that inits the map is called sendSMS which sends a code to the user, after successful authentication a function called toggleMap() is fired which changes the UI.
-
I'm getting an error that says the sendSMS() was called on null. I looked into this on stack but nothing I found nothing relevant to my issue.
Here is the UI code that accepts the SMS prior to changing th UI to map view --
String validatePhone(number) {
RegExp PhoneRule =
RegExp(r'^\d{10}
}
