A tool to migrate API usage to Dart 2.

What does it do?

dart2_fix migrates API usage from Dart 1 code to Dart 2 code. Currently, it focuses on updating deprecated constant names (like dart:convert's UTF8 to utf8).

How do I use it?

To install, run pub global activate dart2_fix. Then, from your project directory, run:

pub global run dart2_fix

When run without any arguments, it will check your project, but will not make changes; it'll indicate what would be changed if asked to make modifications. For example:

test/test/runner/load_suite_test.dart
  line 56 • Duration.ZERO => Duration.zero
  line 60 • Duration.ZERO => Duration.zero
  line 86 • Duration.ZERO => Duration.zero

test/tool/host.dart
  line 169 • JSON => json
  line 173 • JSON => json

Found 5 fixes in 2.3s.

To apply these fixes, run again using the --apply argument.

To actually modify your project source code, run with the --apply argument (pub global run dart2_fix --apply):

Updating test...

test/test/runner/load_suite_test.dart

test/tool/host.dart

then - to check your code - run:
