✐ Examples

1 Getting file path from a file URI

In this example,

  1. We create a file URI using `Uri.parse()`.
  2. We use the `toFilePath()` method to get the file path.
  3. We then print the file path.

Dart Program

void main() {
  Uri fileUri = Uri.parse('file:///path/to/file.txt');
  String filePath = fileUri.toFilePath();
  print('File Path: $filePath');
}

Output

File Path: /path/to/file.txt

2 Getting Windows file path

  1. We create a file URI using `Uri.parse()` with a Windows-style path.
  2. We use the `toFilePath(windows: true)` method to get the Windows file path.
  3. We then print the Windows file path.

Dart Program

void main() {
  Uri fileUri = Uri.parse('file:///C:/Users/User/Documents/file.txt');
  String windowsPath = fileUri.toFilePath(windows: true);
  print('Windows Path: $windowsPath');
}

Output

Windows Path: C:\Users\User\Documents\file.txt

3 Getting Posix file path

In this example,

  1. We create a file URI using `Uri.parse()` with a Posix-style path.
