@ishvar99 2.0.9 introduces android 11 support hence you’ll need a compatible gradle version as mentioned in the changelog.

Regarding your version question, it’s not the plugin that decides which version is picked but pub get instead. Using carrot ^ operator will always fetch the latest minor versions. If you want specifically the 2.0.8 you must use it without the ^.

file_picker: 2.0.8+1

Thanks.

Hi @callingmybluff, this is one of the most known “non-issue” that randomly happens for some yet to find reason but it’s likely related with cached dependencies or gradle conflicts.

Good news is that cleaning and building should be enough, other than that, check these steps and see if it works for you.

Make sure you’re on the latest plugin version as well.

miguelpruivo on 23 Oct 2020

Also if nothing works, try updating your project’s gradle version to version 4.0.1.

Keep me posted and let me know if it worked for you.

I have the same problem, and it was resolved here.

@crdornelles so changing the gradle version was the definitive fix for you?

miguelpruivo on 23 Oct 2020

@miguelpruivo I'm using gradle version 5.6.2 and still having the same issue. I have also tried flutter clean several times and
I'm using flutter version 1.22.2. It was working fine before the update.

No. It's compile, but does not work in devices. Just on debug.

crdornelles on 23 Oct 2020

This issue is in file_picker versions 2.0.9 onwards because file_picker 2.0.8+1 is working fine, but the pubspec.yaml file always fetches the latest version of this package irrespective of the version specified.

@miguelpruivo Thanks a lot, changing the version does the trick for me.

ishvar99 on 23 Oct 2020

I don't think gradle is the problem:

#Fri Jun 23 08:50:38 CEST 2017
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.2-all.zip

Also

  ...
  file_picker: ^2.0.10
  ...

And I still get the same error (updated the main thread to include it):

The built failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetfier to solve the
incompatibility.

Do you know what worked? Downgrading to 2.0.8+1

callingmybluff on 23 Oct 2020

What if you use gradle 4.0.1 with

distributionUrl=https\://services.gradle.org/distributions/gradle-6.1.1-all.zip

This will always be hard to handle as this is a coin with two sides: on one, people will be using later android versions and need the plugin to be updated accordingly or else will find build issues, on other, older versions will experience the same if the plugin is updated.

I must prior the first as people will eventually update as well.

miguelpruivo on 23 Oct 2020

I do confirm it worked with that and latest version of file_picker.

For future users:

gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-6.1.1-all.zip

app/android/build.gradle

    dependencies {
        classpath 'com.android.tools.build:gradle:4.0.1'
...

And finally file_picker: ^2.0.10 in pubspec.yaml

Thanks for your help!

🚀2 👎2

Even that the ticket is already closed, I would like to bring a discussion here:
Based on the SEMVER definition:

Given a version number MAJOR.MINOR.PATCH, increment the:

MAJOR version when you make incompatible API changes,

MINOR version when you add functionality in a backwards compatible manner, and

PATCH version when you make backwards compatible bug fixes.

Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format.

If the change is about including a new functionality that is backwards compatible, it should be a MINOR, not a PATCH.
If you need to change your gradle file to make it continue working, this means that it's a MAJOR change.

That's exactly why the pub get uses the ^ symbol to get only for MINOR changes: you "guarantee" that it will not break any current behavior. Which is totally not the case.

@Cussa that’s correct, and you can see all of those practices that have been rigid followed in my changelog since early days. However, didn’t know that such change wouldn’t be backwards compatible and that such would require explicitly gradle upgrade — that conclusion was only reached with further investigation regarding this issue.

Sorry for any inconvenience.
