How to integrate this library?

[hasnainusti]

Hi, please guide me how can I integrate this library into my project? I cloned the example project and I was able to run it successfully but I don't know how to integrate it into my project. I'm having issue with adding the line animator in pubspec.yaml file.Please help

Hi, I think you would have something like...

flutter_map_line_editor:
  git:
    url: https://github.com/ibrierley/flutter_map_line_editor.git

[hasnainusti]

Thanks. I've successfully integrated it but when I import the library its giving me this warning:

The library 'package:line_animator/line_animator.dart' is legacy, and should not be imported into a null safe library.
Try migrating the imported library.

Strange, it should be updated to nullsafety. Are you using the master branch ?

[hasnainusti]

No. I'm on 2.5.3. Also getting this error on console .

Error: Cannot run with sound null safety, because the following dependencies
don't support null safety:

• package:line_animator

For solutions, see https://dart.dev/go/unsound-null-safety

[ibrierley]

Strange, it should be updated to null safety, and I've tested it with flutter sdk 2.5.2 and 2.8.0.

What happens if you run flutter pub outdated --mode=null-safety ?

(I get direct dependencies: all support null safety. All dependencies opt in to null-safety.)

What does flutter pub deps show out of interest ?

[hasnainusti]

This is the output:

[✗] indicates versions without null safety support.

Doh ignore me, I didn't even read this as the right github repo, I was looking at line_editor which I do, not line_animator. My stupid mistake. Thanks for this. I'll take a look later, probably won't be such a quick fix, but I will take a look when I get time within the next day or so hopefully.

[ibrierley]

I've done some updates, so you could try it now.

[hasnainusti]

That was quick. Well still getting errors. I think you updated the code but didn't upgrade the environment sdk to the null safety one in pubspec.yaml file.

[ibrierley]

Ah yes, well spotted, see if that's better.

[hasnainusti]

Thanks. It's working. Can you please also update the example with null safety?

[ibrierley]

Is it ok now ?

[hasnainusti]

Yes but I'm getting null error on LatLng markerPoint and List points.

[ibrierley]

Sure you have updated it correctly, as line 36 initialises it, so not sure it can be null (and I don't get an error, so seems odd), but maybe I'm looking at something different ?

https://github.com/ibrierley/line_animator/blob/master/example/lib/flutter_map_line_animator.dart

Are you running example/lib/flutter_map_line_animator.dart ?

[hasnainusti]

It's working now. I was using the old code. Thanks man

[ibrierley]

Super, thanks for the update and the patience.
