print_to_log 1.0.0

Migrates debugPrint and print calls in a Flutter or Dart package to package:logging. Add it as a dev dependency and run `dart run print_to_log`.

Using print_to_log

print_to_log can run as a dev dependency of the package you want to migrate, or as an independent, globally installed tool. Both give the same result.

As a dev dependency

Add it to the Flutter or Dart package you want to migrate:

dev_dependencies:
  print_to_log: ^1.0.0

Then, from that package's root:

flutter pub get                  # or: dart pub get
dart run print_to_log --dry-run  # preview the changes
dart run print_to_log            # migrate, then verify with the analyzer

Once the migration is done you can remove print_to_log from dev_dependencies.

As an independent tool

Install it once, then run it on any package without changing its pubspec.yaml:

dart pub global activate print_to_log
print_to_log --dry-run /path/to/flutter_package
print_to_log /path/to/flutter_package

Run from inside the package, print_to_log alone migrates the current directory.

What changes

A file like

import 'package:flutter/foundation.dart';

class Counter {
  int value = 0;

  void increment() {
    value++;
    debugPrint('Counter incremented to $value');
  }
}

becomes

import 'package:logging/logging.dart';

class Counter {
  static final log = Logger('Counter');

  int value = 0;

  void increment() {
    value++;
    log.fine(
      () =>
          'Counter incremented to $value',
    );
  }
}

and logging is added to your dependencies.
