Process run helpers for Linux/Win/Mac and which like feature for finding executables.
Process run helpers for Linux/Win/Mac.
Process.run does not stream output which is not convenient for lengthy
operation. It requires using
Process.start in a more complex way.
runCmd add verbose helper for that. Also dart binaries (pub, dart2js...) and any
script can be called consistently on Mac/Windows/Linux
ProcessCmd allow creating command object that can be run and modified.
Additional options to
- specifying stdin
- making it verbose
- It tries to resolve simple command like
flutter, or any script available on the user path on any Platform.
Display dart version and the command executed:
await run('dart', ['--version'], verbose: true);
which, it searches for installed executables
var flutterExectutable = whichSync('flutter'); var firebaseExectutable = whichSync('firebase');
Allows to run script from Mac/Windows/Linux in a portable way. Empty lines are added for lisibility
Run a simple script:
var shell = Shell(); await shell.run(''' # Display some text echo Hello # Display dart version dart --version # Display pub version pub --version ''');
