It seems that this error is caused by the use of undefined registrar variable in Java code of file_picker plugin, which leads to compilation failure.

According to the error message, the problem lies in lines 257 and 260 of the' FilePickerPlugin.java' file. The code tries to access a variable named' registrar', but this variable is not defined.

Facing same issue, any solution?

[jacklee1995]

Try running flutter clean, and be careful to delete the .lock file in your project first. Then modify the version number, and finally run flutter pub get again.

[jacklee1995]

In addition, the last working version I tried was 8.13.

Back to version 8.13, do not use 8.14 or 8.15.

Do you know how to downgrade the version ? I can't downgrade even though I changed the version in pubspec.yaml

You need to specify a specific version, don't use "^"，in this way, you will not be automatically upgraded to 8.1.5.

Same issue happens with me

[rufus-op]

you can use this repo i have fixed the issue

https://github.com/rufus-op/file_picker

replace

file_picker: 8.1.5

with

file_picker:
git:
url: https://github.com/rufus-op/file_picker

First of all,
There's no such version 8.13 or 8.14, it's 8.1.3, 8.1.4 and 8.1.5.

Secondly, the issue is: registrar variable is not defined in FilePickerPlugin.java file (version 8.1.5)
but the same file in version 8.1.4 doesn't have that variable hence it is working perfectly fine (Version 8.1.4)

Therefore, till the issue gets fixed, you can use version 8.1.4.

Bro, you didn't fork the repo but copied it, and simply overwrote stuff??? rufus-op/file_picker@05992a8#diff-c693279643b8cd5d248172d9c22cb7cf4ed163a3c98c8a3f69c2717edd3eacb7R3
What are all the changes?

Everything should be just a few lines like it is in #1644

Guys, don't use that code, use the PR code like so: #1643 (comment)

[TharinduHub]

First of all, There's no such version 8.13 or 8.14, it's 8.1.3, 8.1.4 and 8.1.5.

this helps!
