Read in Dart

In Dart, we can read a file using the dart:io library, which provides a File class. We can create an instance of this class by specifying the file path and then read the contents using the readAsString method.

Here's an example:

import 'dart:io';
void main() async {

  final file = File('example.txt');

  final content = await file.readAsString();

  print(content);

}

In this example, we're first creating an instance of the File class and passing in the relative path of the file we want to read (example.txt). Then, we're using the readAsString method to read the contents of the file as a string. Finally, we're printing the contents to the console.

If you need to read a binary file, you can use the readAsBytes method instead of readAsString.

import 'dart:io';
void main() async {

  final file = File('example.bin');

  final content = await file.readAsBytes();

  print(content);

}

This will read the contents of the example.bin file as raw bytes and print them to the console.

It's important to note that reading a file is an asynchronous operation in Dart, so the readAsString or readAsBytes methods return a Future that needs to be awaited.
