How can interact with process on dart? - dart

Question

How can put username and password on git command?
I`m try this, but, only the stderr listener is called, with the output error described above and exit code 128
The output error:
fatal: could not read Password for 'https://username#bitbucket.org': No such device or address
void shell() async {
var process = await Process.start('git', ["remote", "show", "origin",],
workingDirectory: "directory/repot");
process.stdout.transform(utf8.decoder).listen((event) {
if(event.contains("Password")) {
process.stdin.write("123456789");
} else if(event.contains("Username")) {
process.stdin.write("user.name");
} else {
print("output git command: " + event);
}
});
process.stderr.transform(utf8.decoder).listen((event) {
print("output erro: " + event);
});
process.exitCode.then((event) {
print("exitcode: " + event);
});
}

Answer 1

I think the code logic runs well try these steps to fix your problem:
Run the commands without the code with your terminal and get a full understanding of all commands and their errors.
Try another way to use a repository that's required passwords and usernames in bitbucket like this example in question with answers
or in Github
git clone https://username:password#github.com/username/repository.git

Answer 2

With Dart, you can interact,
With processes that are quite intact,
You start a Git command with ease,
And handle output with such finesse,
You listen for standard out and error,
And handle them with proper decor,
When "Password" or "Username" appears,
You write them with no room for fears,
But error occurred, as we can see,
"No such device or address" is the key,
But do not fret, for there's a fix,
Store creds in Git config, that's the tricks
or use the ssh key based authentication,
it will give you a smooth operation.
