Using flutter-searchbox in a Flutter module it doesn't work

[FDavidse20]

Hi @bietkul , it's Filip from Funda again:

When using flutter-searchbox in a Flutter module it doesn't work anymore after the recent updates to incorporate null-safety.
steps to reproduce:

• in Android Studio choose New -> New Flutter Project to create a new Flutter Module (nót a Flutter application).
• in the new module add in the pubspec

flutter_searchbox: ^2.0.0-nullsafety
searchbase: ^2.0.1

• flutter pub get
• flutter run (with iOS simulator)
  and the following error occurs:

@FDavidse20 There is already an issue reported at here. It is more likely an issue with the flutter module created by android studio. If you can spend some time then I would recommend trying the following things:

• Create a flutter module without android studio so it can use the latest flutter dependencies - speech_to_text does not specify a Swift version and none of the targets (Runner) integrating it have the SWIFT_VERSION attribute set. csdcorp/speech_to_text#88 (comment)
• - speech_to_text does not specify a Swift version and none of the targets (Runner) integrating it have the SWIFT_VERSION attribute set. csdcorp/speech_to_text#88 (comment)

Let us know if none of them work. We'll check on this.

I've also published a version(2.0.1-without-speech) without the speech_to_text package so you can continue the development.

@bietkul, thank you for the reply.
Creating the module from the command line instead of with Android studio fixed the problem for me.
But I think it would be an interesting idea to separate some of the functionality/dependencies from the flutter-searchbox.
For example, I'll be hooking up the functionality of it with my own custom widgets. Meaning I'm not using the out of the box search widget with dropdown and speech to text functionality.
What do you think about having the different functionalities that are now within flutter-searchbox spread out over multiple packages?

@FDavidse20 I think flutter supports tree-shaking so it won't include the unused classes. I found a good article on this https://medium.com/flutter/optimizing-performance-in-flutter-web-apps-with-tree-shaking-and-deferred-loading-535fbe3cd674.
We can lazy load the speect_to_text library to load the app faster.
