Hi, I'm following the udemy course and have problems cloning this.
I can download and extract, but the process of cloning itself is causing an error and I'm curious what the issue is, to solve this for the future.
This is the error:

After Cloning down the repo, trying to run gives me this error

Because mi_card depends on flutter_test any from sdk which doesn't exist (the Flutter SDK is not available), version solving failed.

Flutter users should run flutter pub get instead of pub get.

@angelabauer would it be possible for you guys to update this (and I assume other) code to make it usable with the latest version of flutter? Cheers!

I followed the steps provided by app brewery. But I get this message as soon as I launch the fluuter project in android studio

For those who are now starting this project, there are some changed you have to do to your YAML file for the dependencies to resolve.

change cupertino_icons to

cupertino_icons: ^1.0.6

and change sdk to

sdk: ">=2.12.0 <4.0.0"

make sure spacing is correct for each.

This updates the package manager to get the latest changes for Mi Card to work

Open android > gradle > gradle-wrapper.properties
change --> distributionUrl=https://services.gradle.org/distributions/gradle-7.0.2-all.zip
to --> distributionUrl=https://services.gradle.org/distributions/gradle-7.6-all.zip

Open android > app > build.gradle and then change both compileSdkVersion and targetSdkVersion to 31

Then open android > app > src > main > AndroidManifest.xml . Under the activity tag add android:exported="true" at the end.

Re-run you app and it should work

what should i do ?
please , step by step i am begginer

App throws up issues after cloning. Issues ranging from assembleDebug fail and so on.

after cloning the project from this repo into my local machine i was unable to run it in an emulator, whenever i try to run it i get this error.

• The name of a constructor must match the name of the enclosing class.
• Expected an identifier.

I was also having cloning problems Initially and was getting this error.
My Setup - Windows 10, Android Studio Version

Error - The minCompileSdk (31) specified in a dependency's AAR metadata (META-INF/com/android/build/gradle/aar-metadata.properties) is greater than this module's compileSdkVersion (android-29).

I could have created a new PR but I think the new commit was made for MacOS users specifically

Solution - Checkout your project to the initial commit and create a new branch.
Command - git checkout -b new_branch b7f3aa688bf398829a4de914273d3162b300cb4c

Try Building the project again. It should work now

Android version 4.0.1 is not showing 'get dependencies' option at top.

hi, i just wanted to point it out that app icons are not set for android, you might want to add this to the repository.

No matter what I've tried with the mi_card_flutter it will not load images either if its a network image. Every time I run it comes up with a whole list of excepts that are pointing to the assets_build.dart
There is no faults in the yaml file and I have looked at everything in stack over flow and tried everything that has been advised but still fails to load and still brings up the assets_build.dart.
Can someone please help me as I'm at the point of pulling my hair out

What you'd expect if these materials aren't updated in face of changes like iOS 14. IPHONEOS_DEPLOYMENT_TARGET is set to 8.0, which leads xcode to throw errors when trying to build.

something is missing on the project. I'm working on an android studio. I cannot run the app.

Running Gradle task 'assembleDebug'...
stuck in this for infinity time

It seems a lot of people are having issues cloning the mi_card project, and later projects too.
I have hopefully found a way to resolve this:

Problems getting projects to open up from Version Control? Files seem to be missing? The code looks different to the tutorial when you open the project up after cloning? Try this!

1. Open the cloned project in Android Studio.
2. Now find the cloned files in a separate documents window (not in Android Studio).
3. Within the documentation, find a file in here called 'main.dart' (probably in the folder named lib).
4. Drag and drop the main.dart file into the space on Android Studio where you write the code. This should bring up the code as it appears in the tutorial.
5. It may now say that Dart SDK is not configured. If it does, in Android Studio go to File>Settings>Languages & Frameworks>Dart.
6. Click on the box 'Enable Dart support for the project ….........'
7. You will need to input the Dart SDK path. This is probably: C:\src\flutter\flutter\bin\cache\dart-sdk
8. If the above path suggestion doesn't work, open up a different, working Flutter project in Android studio. Find the correct path within this project - File>Settings>Languages & Frameworks>Dart.
9. Copy and paste the path from this working project into the project you are trying to get to work.
10. Then click the boxes 'Enable Dart Support for the following modules.
11. Click 'OK'
12. It should now work.
13. Remember to now click 'Get Dependencies' at top of the screen

I really do help this solves your issues Flutterers! Please do reply if the solution worked for you.

Thanks,
Alex

Hey guys.
So I have been following the tutorial for the mi_card and having issues after cloning.
The folder is saved on my computer but a lot of folders are missing and I keep getting the "File not found: git.exe" error.
Please help.

Wasn't able to get program to work on virtual android device. Tracked the problem down to needing to update project to work with AndroidX.

*To get these working as is, I had to open the internal project's "android" file up as an existing project (not the mi_card_flutter file). Go into build.gradle and change compileSdkVersion to at least "28", then in Android Studio menu Refactor -> AndroidX and update any thing else that pops up.

After doing this the project would work, so these projects should probably be updated at their root.

Build failed with an exception.

• What went wrong:
  Could not open settings generic class cache for settings file 'C:\Users\vijet\StudioProjects\mi_card_flutter\android\settings.gradle' (C:\Users\vijet.gradle\caches\7.0.2\scripts\9ro1u0k9hdyieqwldgdt37f3r).

BUG! exception in phase 'semantic analysis' in source unit 'BuildScript' Unsupported class file major version 61

• Try:

Exception: Gradle task assembleDebug failed with exit code 1

The lower bound of "sdk: '>=2.1.0 <3.0.0'" must be 2.12.0'
or higher to enable null safety.

The current Dart SDK (3.1.0) only supports null safety.

I cloned mi_card_flutter to my computer, but it won't compile. Tried to install and upgrade the dependencies also not worked for me.

Comparing cloned(left) and created a new flutter project(right), it seems there are many files missing on this git repository.

I go the page and no matter where I dig and look I cannot find the content needed for the Flutter course. I need the MiCard content!

This error is showing .please help!!!!
