dependency_overrides: pull_to_refresh: git: url: https://github.com/miquelbeltran/flutter_pulltorefresh

this doesn't work for me.
when i try to 'flutter pub get' i have this error:

Because myProject depends on dependency_overrides from unknown source "pull_to_refresh", version solving failed.
pub get failed (1; Because myProject depends on dependency_overrides from unknown source "pull_to_refresh", version solving failed.)

[mdeimert]

@nixonoftheyear

Use it like this:

dependency_overrides:
pull_to_refresh:
git:
url: https://github.com/miquelbeltran/flutter_pulltorefresh
ref: master

[nixonoftheyear]

@nixonoftheyear

Use it like this:

dependency_overrides: pull_to_refresh: git: url: https://github.com/miquelbeltran/flutter_pulltorefresh ref: master

another error now:
Because myProject depends on dependency_overrides from unknown source "pull_to_refresh", version solving failed.
is there any command for enable unknow source or anything similar?

[mdeimert]

You have original dependency added in dependencies?

dependencies:
pull_to_refresh: ^2.0.0

dependency_overrides:
pull_to_refresh:
git:
url: https://github.com/miquelbeltran/flutter_pulltorefresh
ref: master

This one works for me without any issue.

[mdeimert]

Also please remember that spacing/tabulation in yaml file is important the dependency_overrides needs to be at the same level as dependencies.

Like this:

resolved! i was wrong to align dependency_overrides as the daughter of dependencies. thank you!
is it normal that the flutter pub get takes a long time (72 seconds instead 3 seconds)?

Great :)

Could be if fetching first time some repo.

[cybrox]

While I greatly appreciate miquelbeltran's effort on providing a fork, I urge people to use ref: 6d7fbdd instead of just ref: master in your dependency overrides.

Using ref: master means whatever is commited to that repository is bundled and delivered in your application, no questions asked.

[miquelbeltran]

Hi everyone! I don't endorse the use of my fork (because I don't plan on maintaining it), instead, please insist on the library authors to merge this PR: #589
