Flutter：带有BottomNavigationBar的ArrayIndexOutOfBoundsException

Question

I'm following to this tutorial: https://github.com/fablue/building-a-social-network-with-flutter and I completely copied and pasted the "Resume" section, but it stops with these errors.

Error reading dependency file C:\Users\ritar\AndroidStudioProjects\practice_google_plus\build\app\intermediates\flutter\debug\snapshot_blob.bin.d: java.lang.ArrayIndexOutOfBoundsException: 1

I'm glad if you can tell me how to make it work.

Answer 1

This package is not maintained anymore and outdated. It was developed for the early flutter and does not use Dart 2. Also the Readme says:

This project tutorial is OUT OF DATE. It was created with a very early version of flutter and I am not able to maintain it

Here is an issue that describes your problem.

Answer 2

Seems this problem is related with /build directory. Run:

flutter clean //removes your /build directory
flutter run

As documented in this issue
