Flutter HERE maps here_sdk not loading map. White screen only. Happens in all apps, INCLUDING their OFFICIAL here_map_app example

Issue

Using the Flutter here_sdk doesn't work. Specifically, the HERE hello_map_app example only shows a white screen when loading.

I am using the Explore here_sdk. Here is the top of its pubspec.yaml:

name: here_sdk
description: HERE SDK for Flutter
version: 4.21.5
homepage: https://here.com

I've followed these Getting Started steps meticulously, including ensuring my API keys are correct (I don't get any incorrect credential errors when loading the app).

These are shown when I run it on my iOS simulator via XCode:

My Ideas

Note

This also happens in any Flutter project I make, but I'm using the official HERE hello_map_app example so its reproducible.

Solution

  • here_sdk doesn't seem to support Flutter 3.29 yet.
