How to generate Dart code from json structure
The code_build
(https://pub.dartlang.org/packages/code_builde) package provides a solution to generate classes and constructors, field and methods for that class.
My ultimate goal is to generate Flutter (https://flutter.io) Widgets based on the json structure given, but I don't know how to do this with the code_build
or another package.
So help would be appreciated!

The general way to write something which outputs Dart code is to wrap up the functionality in a Builder
and to perform the code generation with build_runner
At a high level you'd write a Builder
that:
- Has
buildExtensions
of{".json": [".dart"]}
. - Reads in the
buildStep.inputId
asset and parses the json. - Uses
code_builder
to build up a String and then write it to the output asset.
Then you'd configure the builder in build.yaml
. And either apply it manually to your package, or if you'd like to publish it as a utility it can apply to dependencies.
Your package would have a dev_dependency
on build_runner
and then you can execute builds with flutter packages run build_runner build
.
There are more docs at https://github.com/dart-lang/build/tree/master/docs
You can see an example of a package which does something similar - starts with yaml files and outputs Dart files using code_builder
at https://github.com/natebosch/message_builder
