Add Error started after adding Hive packages.
After when I go back to the copy before Hive it worked fine !!!
Any help?!

[dryasbk]

Changed it to pdf_render: ^1.0.12 , worked fine

[jafar260698]

I have also the same error , how to handle it ?

[devmaxde]

Downgrade Flutter

[JmyW]

Changed it to pdf_render: ^1.0.12 , worked fine

I changed to pdf_render too, due to NullPointerException issue. The pdf_render works very well.

[a914-gowtham]

use this package instead pdf_render
