Need to the new version on the pub.dev to avoid error:
Because every version of isolate_bloc depends on uuid ^2.2.0 which depends on crypto ^2.0.0, every version of isolate_bloc requires crypto ^2.0.0.
And because pdf >=3.0.1 depends on crypto ^3.0.0, isolate_bloc is incompatible with pdf >=3.0.1.
So, because app_name depends on both pdf ^3.2.0 and isolate_bloc ^1.0.4, version solving failed.
