How to use

To use this package, start by reading the content of a pubspec.yaml or pubspec.lock file. Then, import the finder function and feed it the file content.

import { default as finder } from 'flutter-version-finder';
import { readFileSync } from 'fs';

// Read the content of a pubspec.yaml or pubspec.lock file
const path = 'example/example.lock';

const data = readFileSync(path).toString();

// Find the matching Flutter version
const result = finder(data);

// Hoooraaaay! It should print the Flutter version that is compatible with the lock file
console.log(result); // { flutter: '3.10.0', dart: '3.0.0' }

Additionally, you can finder Flutter versions directly from the CLI:

npx flutter-version-finder --path=example/example.lock
