Flutterfire throws a dart not found error

Question

I'm following the flutter + firebase codelab, and I'm stuck at configuring firebase in my android app, I've already installed the flutterfire cli globally on my machine and exported the bin in my path.

export PATH="$PATH:~/source/flutter/bin"
export PATH="$PATH":"$HOME/.pub-cache/bin"

But still, the following error is thrown when I try to use the flutterfire cli.

flutterfire
/home/dio/.pub-cache/bin/flutterfire: 8: dart: not found

This error leads me to believe that dart is not installed on my system but....

Answer 1

I was able to work around this issue by calling the bin directly, like so:

dart /home/foo/.pub-cache/global_packages/flutterfire_cli/bin/flutterfire.dart-2.17.0-239.0.dev.snapshot configure

This is weird since I'm calling the cli through the same path specified in at ~/.pub-cache/bin/flutterfire

  dart "/home/foo/.pub-cache/global_packages/flutterfire_cli/bin/flutterfire.dart-2.17.0-239.0.dev.snapshot" "$@"

I was facing this same problem, so I looked into the file that stores the code for flutter fire command in bash.

This file is stored in the ~/.pub-cache/bin/ I looked up the code inside this file. What the code basically does is, it passes over whatever command that you have given, to this other command

dart pub global run flutterfire_cli:flutterfire{your command}

So, if you want to run a command say, flutterfire configure , you can run it this way,

dart pub global run flutterfire_cli:flutterfire configure

I hope this answer helps!!.
