I had to recreate my project and paste the files into it and it worked.
FAILURE: Build failed with an exception.

• What went wrong:
  Could not determine the dependencies of task ':app:compileDebugJavaWithJavac'.

Failed to install the following SDK components:
platforms;android-29 Android SDK Platform 29
The SDK directory is not writable (C:\Program Files (x86)\Android\android-sdk)

It looks like commit 8a469c21cfe75c08079c7aad9d46689dba5369f6 was supposed to add the icon files, but the actual files were not added to git.

Your Flutter application is created using an older version of the Android embedding. It's being deprecated in favor of Android embedding v2.
I am experiencing this issue constantly while making every app and it's getting very frustrating to fix it every time and even then it doesn't work properly.
Please help Angela!!

that is the error it showed

I thought it should be for choice 2 instead of choice 1:
//TODO: Step 14 - Use the storyBrain to get the text for choice 1.

It says
//TODO: Step 14 - Use the storyBrain to get the text for choice 1.
expected to say
//TODO: Step 14 - Use the storyBrain to get the text for choice 2.

in the mi_card_flutter if I try to add images wether its a network image or a asset image it throws up so many issues,
the yaml file is ok when run pub get, the main dart file is not showing any typos but no mater what I try it will not load image and flags up over 50 exceptions within the asset_bundle.dart. I have tried everything on stack overflow and now on verge of binning this course

remove
import 'dart:html'; from main.dart
