Supports parsing pubspec.lock files with robust error reporting

Designed around the pubspec_parse package, and mirrors its implementation and interface

Usage

import 'dart:io';
import 'package:pubspec_lock_parse/pubspec_lock_parse.dart';

void main() {
    final lockStr = File('path/to/pubspec.lock').readAsStringSync();
    final lockfile = PubspecLock.parse(lockStr);
}

You can find more about the PubspecLock object in the documentation here

toJson() methods

pubspec_lock_parse includes .toJson() methods on each object to allow for easy re-generation/mutation of pubspec files

This can be combined with yaml_writer to re-generate yaml output

void main() {
    final pubspec = PubspecLock(
        packages: {
            'somePackage': Package(
                dependency: 'transitive',
                description: PathPackageDescription(
                    path: '../somePackage',
                    relative: true,
                )
            )
        },
        sdks: {
            'dart': VersionConstraint.parse(">=2.17.0 <3.0.0"),
        }
    );

    final jsonPubspec = pubspec.toJson(); // outputs Map<String, dynamic>
    final yamlPubspec = YamlWriter().write(jsonPubspec); // outputs String
}

toJson can also be run on any individual object

// outputs: { path: '../somePackage', relative: true }
print(PathPackageDescription(
    path: '../somePackage',
    relative: true,
).toJson());
