File path in Dart

In Dart, to get the path of a file, we can use the path package. This package provides several methods to work with file paths.

Here's an example of how to get a file path in Dart:

import 'package:path/path.dart' as path;
void main() {

  // Absolute path

  String absPath = '/home/user/example/file.txt';

  

  // Relative path

  String relPath = 'example/file.txt';

  

  // Get the basename of the file

  String basename = path.basename(relPath);

  

  // Get the directory name of the file

  String dirname = path.dirname(relPath);

  

  // Join paths

  String newPath = path.join(dirname, basename);

  

  print('Absolute path: $absPath');

  print('Relative path: $relPath');

  print('Basename: $basename');

  print('Directory name: $dirname');

  print('New path: $newPath');

}

This will output:

Absolute path: /home/user/example/file.txt
Relative path: example/file.txt
Basename: file.txt
Directory name: example
New path: example/file.txt

In the example above, we first import the path package and create two variables absPath and relPath for the absolute and relative file paths, respectively.

We then use the path.basename() method to get the basename (i.e., the file name with extension) of the file and the path.dirname() method to get the directory name of the file.

We can join the directory name and basename using the path.join() method to get the full file path.

Finally, we print out the results for each variable using the print() method.
