Hy, I am new to flutter and while working with an app that uses image_picker to get images from the gallery I was facing this error.

I have the following directory/package structure in my groovy project:
src
+ progressManagers (package)
| |
| + LoadSensitiveProgressManager.groovy
+ TemporaryRegistry.groovy
Contents of TemporaryRegistry.groovy
// here is no package definition set
public class TemporaryRegistry {}
Contents of LoadSensitiveProgressManager.groovy
package progressManagers
// this gets marked red in my IDE (Intellij Idea)
import TemporaryRegistry
class LoadSensitiveProgressManager implements GenericProgressManager {
}
When i run my code in Scriptrunner for Jira Server the class is not found:
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
file:/data/atlassian/application-data/jira/scripts/progressManagers/LoadSensitiveProgressManager.groovy: 7: unable to resolve class TemporaryRegistry
# line 7, column 1.
import TemporaryRegistry

1 error
Why is that?
I can "import TemporaryRegistry" from every groovy file in the src folder.
Thanks in advance

I want to add Google Analytic to my flutter app.
this a walk trough that I fallow (Add Analytics to Your Android App
)
when I do the steps of the linked help, I got error in build process,
and my IDE doesn't resolve these imports:
import com.google.android.gms.analytics.GoogleAnalytics;
import com.google.android.gms.analytics.Tracker;
I put here my project files:
MainActivity.java:
package com.example.flutterapp;

import io.flutter.app.FlutterActivity;
import io.flutter.plugins.GeneratedPluginRegistrant;
import com.google.android.gms.analytics.GoogleAnalytics;

public class MainActivity extends FlutterActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
GeneratedPluginRegistrant.registerWith(this);
}
// Obtain the shared Tracker instance.
AnalyticsApplication application = (AnalyticsApplication)
getApplication();
private static Tracker mTracker = application.getDefaultTracker();
mTracker.setScreenName("home");
mTracker.send(new HitBuilders.ScreenViewBuilder().build());
}
AnalyticsApplication.java:
package com.example.flutterapp;
import android.app.Application;
import com.google.android.gms.analytics.GoogleAnalytics;
import com.google.android.gms.analytics.Tracker;
public class AnalyticsApplication extends Application {
private static GoogleAnalytics sAnalytics;
private static Tracker sTracker;
#Override
public void onCreate() {
super.onCreate();
sAnalytics = GoogleAnalytics.getInstance(this);
}
/**
* Gets the default {#link Tracker} for this {#link Application}.
* #return tracker
*/
synchronized public Tracker getDefaultTracker() {
// To enable debug logging use: adb shell setprop log.tag.GAv4 DEBUG
if (sTracker == null) {
sTracker = sAnalytics.newTracker(R.xml.global_tracker);
}
return sTracker;
}
}

how Can I solve this problem?
please help me, thank you.
I think it's because of AndroidX compatibility. You can try to change to older version of dependency. That helped me for some dependencies.
I use Mac OSX Sierra, and am trying to install matplotlib in python 3.7, and therefore use
pip3.7 install matplotlib
But that gives me an error

I meet the same problem on Spark 2.0.0. I think the reason is that file 'external\flume-sink\src\main\avro\sparkflume.avdl' is not complied well.
The problem can be resolved by:
Download Apache Avro
http://avro.apache.org/docs/current/gettingstartedjava.html
I downloaded all jar files into folder 'C:\Downloads\avro'.
Go to folder 'external\flume-sink\src\main\avro'
compile sparkflume.avdl to java files
java -jar C:\Downloads\avro\avro-tools-1.8.1.jar idl sparkflume.avdl > sparkflume.avpr
java -jar C:\Downloads\avro\avro-tools-1.8.1.jar compile -string protocol sparkflume.avpr ..\scala
recompile your projects.
