Instance of 'InstantiationException' on Landing Screen #105

Closed Dehmee closed 1 year ago

Dehmee commented 1 year ago

I keep getting an "Instance of 'InstantiationException'" exception whenever I try to run the downloaded project. I have added the HERE SDK to the plugins folder (version: 4.15.2) but it fails every time I run it. The exception comes from assigning the Position Engine userConsentState to the _consentState variable on the landing screen. Here is the full error message:

`======== Exception caught by widgets library ======================================================= The following InstantiationException was thrown building Consumer2<AppPreferences, CustomMapStyleSettings>(dirty, dependencies: [_InheritedProviderScope<AppPreferences?>, _InheritedProviderScope<CustomMapStyleSettings?>, _InheritedTheme, _LocalizationsScope-[GlobalKey#1046e]]): Instance of 'InstantiationException'

The relevant error-causing widget was: Consumer2<AppPreferences, CustomMapStyleSettings> Consumer2:file:///C:/src/here/here_reference_app/here-sdk-ref-app-flutter-master-v.4.15.2/lib/landing_screen.dart:109:12 When the exception was thrown, this was the stack:

Hi, you need to stick to HERE SDK 4.15.0.0. The project integrates only the major versions at the moment, see the readme file for the correct version.

Dehmee commented 1 year ago

Thank you. Please how do I download a specific version of the SDK? Right now 4.15.2 is the one available when downloading from the HERE portal. Where can I download version 4.15.0.0 from?

stefan-troyke commented 1 year ago

Hi, sorry for the inconvenience but it seems our portal only allows to download the current vertsion at the moment. I opened a ticket for this. Please get back to the account manager or the technical cosumer support. They will help you on this matter.
