Issue
I’m installing 2 packages: rxdart and flutter_plugin_pdf_viewer
rxdart: ^0.23.1
flutter_plugin_pdf_viewer: ^1.0.7
but flutter_plugin_pdf_viewer >=1.0.4 is forbidden.
and this is error message:
Because flutter_plugin_pdf_viewer >=1.0.4 depends on rxdart ^0.21.0 and flutterattendancesystem depends on rxdart ^0.23.1, flutter_plugin_pdf_viewer >=1.0.4 is forbidden.
So, because flutterattendancesystem depends on flutter_plugin_pdf_viewer ^1.0.7, version solving failed.
pub upgrade failed (1; So, because flutterattendancesystem dep
ends on flutter_plugin_pdf_viewer ^1.0.7, version solving failed.)
Solution
Look at this thread https://github.com/CrossPT/flutter_plugin_pdf_viewer/issues/59
This repo is not maintained properly,
You can use a different package for pdf viewer.
or for a temporary fix do a following
Manually edit the pubspec.yaml in flutter_plugin_pdf_viewer-1.0.7 folder in .pub-cache and set rxdart: ^0.21.0 to rxdart: ^0.23.1.
In flutter_plugin_pdf_viewer-1.07/lib/src/document.dart at line no: 89, changed Observable to Stream.
