Issues in the finding Flutter widgets

[singlesoup]

Hello, I am using Custom_lint Package. To write some project specific lints. Like I want my team to use a project specific CustomScaffold rather flutter given Scaffold.

But since this is build on top on Dart Analyzer, which has no way of identifying Flutter Widgets, how can we detect Flutter Widgets with this ?

Tried both Element Tree as well as AST, but since in the documentation there was no mention of Flutter widget, it didn't help much. So it would be amazing if you guys could find some time to see how can we detect Flutter widgets with this.

You'll want to visit the AST of the build function. From there, search for an ast is InstanceCreation AST (or something with a similar class name, can't remember exactly which one)

With that done, you can obtain the Element. Doing element is ClassElement will give you info about the class instantiated

I have tried obataining Element from InstanceCreationExpression by visiting Build Class Members, as you mentioned. But was not able to find any Element. Would it be possible for you point me to the direction where I can get Element from Instance Creation?

[rrousselGit]

There's InstanceCreationExpression.staticType which is a DartType. And you can access an Element from with with .element

hey thanks @rrousselGit , was able to solve the issue.

PS: A small suggestion, if this comes in the package documentations that would be amazing for everyone.
