Setting up to develop and encountering issue running build.dart

[ImminentOrbit]

I've read through the setup section and have followed the steps listed. Trying to run the scripts/build.dart in Android Studio, and also via command line, gives me this output:

E:/Programming/flutter/bin/cache/dart-sdk/bin/dart.exe --enable-asserts C:\Users\Orbit\AndroidStudioProjects\thunder\scripts\build.dart
Checking if Flutter is installed...
Unhandled exception:

It is saying it cannot find a file, but I'm not sure which file that is? Any help?

@Arphahat You can tell which file it's having trouble finding by the output of the command.

Command: flutter --version

It's having trouble finding the flutter binary. First, make sure it's in your path. On Windows, I found I also had to update the build script with flutter.bat (and I had to change all the other binary names, too).

P.S. You can use the VS Code extensions for Dart/Flutter and generally avoid the build script (if you just want to debug and not create a release deployment).

Thanks, updating it to use flutter.bat addressed that issue. Looks like there is a new problem trying to run "cider" which I don't think was referenced in the install instructions.

[micahmo]

You might have to run flutter pub global activate cider to install cider. And you may also have to change it to cider.bat in the script.

As @micahmo mentioned, you don't have to run the build script unless you want to generate a release APK/IPA file

If you want to set up your environment for development purposes, usually VSCode's Flutter/Dart extensions will allow you to do that. If you want quicker help, feel free to join in the Matrix space and we can all discuss it there too!

Thanks. It looks to be building, even though it now seems to be unnecessary. I'll take a look at the matrix link.
