Another perfect fit for extension types: file paths. I was writing path handling code and kept messing up due to relative vs absolute paths, and thought ... maybe `AbsolutePath` and `RelativePath` as extensions on `String`? Did exactly what I wanted :) https://t.co/qUL2zsk894

Happy Friday! No revolutionary `build_runner` release this week I'm afraid. Actually I've been sidetracked by `package:watcher` most of these last three weeks or so. It does the file watching in the Dart analyzer and `build_runner`. I've been finding+fixing lots of edge cases

"We were so impressed [by Jaspr] that we migrated our entire documentation infrastructure — both https://t.co/ehHEdj98Xf and https://t.co/w5bl4hbP3h — over to it." I'm beyond grateful for this shout-out by the @FlutterDev team and so happy to finally share this!!

I just released `build_runner 2.10.3` with another performance improvement, if you have a big codebase you will be happy, benchmark results: 1000 files: 2x faster (5s -> 3s) 2000 files: 5x faster (25s -> 5s) 5000 files: 27x faster (424s -> 15s) https://t.co/RKJsGJAEly

Do *NOT* accept such builds times from Flutter. Always check is taking the time, e.g. here this was caused by 1) choice by slang i18n package to generate 1 enormous function with all messages for each locale 2) quadratic behavior in Dart's register allocator cont

Please use Dart outside of Flutter more :)

Another `build_runner` performance improvement published today as `2.10.1`. If `source_gen:combining_builder` (used by json_serializable, built_value, ...) was slow for you it should now be much faster. https://t.co/RKJsGJA6w0

Happy Friday! Was gonna make a bad joke about AOT compiles but I stopped myself JIT.

Released: `build_runner` 2.10.0 which adds AOT compile of builders for faster builds. For now it's behind a flag, write `--force-aot` on the command line for the new mode. Please send any feedback my way, if all goes well it will be on by default in a future release.

Which shell do you use? After bash I used zsh for a while, then fish. I really like fish. https://t.co/jCUtT0xfaG https://t.co/0w9xCUxKsN

I always enjoy when I get to use Dart extension types. Now used internally in `package:watcher` where they add static safety with no runtime cost around use of `FileSystemEvent`. https://t.co/PDYUMVqrHb

Dart: do you use `var` or `final` for locals? I prefer `final`, but it's a long story. https://t.co/ivHHbvRs38

Released `build_runner` 2.9.0. Visible changes: log output, particularly in watch mode, is further streamlined. Behind the scenes: this is a big refactor to how builders are compiled and run in preparation for using AOT compile. So, please let me know if you see any new

Taking over `package:watcher`, which is what `build_runner` and the analyzer use to monitor for file changes. There are some minor bugs and inconsistencies, probably a breaking release will be needed to get everything in line, if you use `package:watcher` you may want to follow

Dart: why would you `omit_local_variable_types`? The lint forces types on the left hand side of a local variable declaration + assignment to be omitted. A lot of the discussion around this and related lints misses what I think is the critical point here: that types on the left

Do you develop plugins for Flutter? Investigating a rare corner case causing IDE/tool slowness, if it affects you, please let me know! - you work on a plugin - you have other packages nested in the plugin package - you "flutter pub get" in the nested packages

Released `build_runner 2.8.0`: - clearer errors if the build fails; highlighted red - removed the "deleting declared outputs" warning - a bunch of internal refactoring/cleanup that 99% of you don't care about :) https://t.co/RKJsGJAEly

If you've ever wanted proper "undefined" behavior, or untagged unions in dart_mappable, you can have it now: https://t.co/G5sovUTvQH

Released built_value 8.12 using the new build_runner "triggers". Files that don't use built_value are skipped quickly as "not triggered". ``` dart run build_runner build 2s built_value_generator:built_value on 1001 inputs: 999 not triggered, 2 output; spent 1s analyzing ``` If

When I tell a dev tool to do something I don't want it to immediately ask me back: how? This mostly happens when there are multiple functionally equivalent way to do the same thing; for example, relative vs package imports in Dart. In such cases I want opinionated tools that
