2024年11月10日 · dart_eval is an extensible bytecode compiler and interpreter for the Dart language, written in Dart, enabling dynamic execution and codepush for Flutter and Dart AOT. The primary aspect of dart_eval 's goal is to be interoperable with real Dart code.

Sometimes you need to load some data before building your widget. Because initState doesn't support asynchronous loading you need to find another way to load your data. The most common way of loading data is using a FutureBuilder but FutureBuilders are tedious. Another way is using flags to rebuild the widget after all the loading is done.

2015年2月17日 · It needs to load code from a third-party package, which is only known at runtime. My application needs to: Ideally, I do not want to require that my users specify the third-party dependency. The application should auto-discover the dependency. For example, a workflow could be something like this:

2025年1月20日 · Automatic hot code reloader for Dart projects that monitors the source files of a Dart project for changes and automatically applies them to the running Dart process.

2014年4月15日 · So, yes, it is possible in Dart to dynamically (re-)load dart-files at runtime. Every new isolate has its own MirrorSystem. If you want to reload a dart-file you must create a new isolate and use the MirrorSystem of this isolate to iterate over the contents in the libraries known to this MirrorSystem.

2013年7月13日 · If you look at (http://dart.googlecode.com/svn/branches/bleeding_edge/dart/client/dart.js), it looks for script tags such as foo.dart and automatically loads foo.dart.js. It does this in a window.addEventListener("DOMContentLoaded", function (e) {...}) callback.

2013年4月23日 · Dart programs are static, in that their shape and structure do not change after they are compiled. A static program is great for optimizations like tree shaking (aka dead code elimination), type-inferencing compilers, and more. However, modular apps often require a way to dynamically load code.

2025年2月12日 · Flutter performs deferred loading when you compile your Android app in release or profile mode, but debug mode treats all deferred components as regular imports. The web creates deferred components as separate *.js files. For a deeper dive into the technical details of how this feature works, see Deferred Components on the Flutter wiki.
