![]() Adds an "eventLog" property to the global "$__dart_deferred_initializers__" object. The event log is just a JS Array that gets initialized alongside $__dart_deferred_initializers__. Each event entry is a String->String JS object. I unified the format of these event objects for easier parsing. Each printed event is now valid JSON (passed through JSON.stringify) so we can more easily post-process the logs if necessary. Fully replacing the existing "_eventLog" field makes the logging logic simpler. Having a single array allows us to not include a timestamp because the array captures the event ordering (actual timing doesn't matter). It also makes it easier to stringify the logs when there's only 1 data source/format. Sample output: ``` {"hunkName":"out.js_1.part.js","event":"loadHunk"} {"uri":"path_to/out.js_1.part.js","hunkName":"out.js_1.part.js","event":"downloadHunk"} {"file":"out.js_1","event":"beginLoadPart"} {"file":"out.js_1","event":"endPartLoad","hash":"aCscY7yv4EHodRPmCqYn5BqMelA="} {"uri":"path_to/out.js_1.part.js","hunkName":"out.js_1.part.js","event":"downloadHunkSuccess"} {"hunkName":"out.js_1.part.js","hash":"aCscY7yv4EHodRPmCqYn5BqMelA=","event":"initialize"} ``` Change-Id: Ifee73be0bf7dc53a0e7710ff033dd2b0fae9fb0e Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/307240 Commit-Queue: Nate Biggs <natebiggs@google.com> Reviewed-by: Stephen Adams <sra@google.com> |

Dart
A client-optimized language for fast apps on any platform
Dart is:
-
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.
-
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.
-
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
-
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
-
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
License & patents
Dart is free and open source.
