Folks,
I am re-building an already built flutter application upon changing of the laptop. However I have strangely observed that the dependencies that we mention in the pubspec, not all of them are getting compiled. Those ones which has native dependencies and eventually have android code base in the dependencies fail to compile. I am cluless how this is happening and where should i look forward to get this going. The only error I get is as below. The contentious dependencies were share and connectivity

I am using flutter 1.22.6 stable
dart 2.10.5
Gradle 6.5
I have tried it out with 1.22.3 and also with 1.20.4, still this is not taking me anywhere. All that it ends up is not compiling the dependencies having android code in it. gradlew assembleDebug --info and likes of it has resulted in me understanding that the java symbols are not created which eventually are not found by the compilation script, hence it is generating error.
things ive done so far:
run with --no-sound-null-safety and --verbose
find dependencies that complain and check for updates, then update to latest in pubspec
one dependency complained about android min sdk version in gradle.build, so i updated accordingly
now i can build to my test machine and work out the runtime bugs!
Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0. Flutter

Not quite certain if it's a single error or multiple, my guess is it has something to do with my gradle any help whatsoever is appreciated.
It's been a while since I have not checked flutter so I am not sure what the error means...
After putting in some hours into this I realized that the issue was with my Activity having the old flutter engine config code, to fix this all i had to do was go from this:
import android.os.Bundle;
import io.flutter.app.FlutterActivity;
import io.flutter.plugins.GeneratedPluginRegistrant;
public class MainActivity extends FlutterActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
GeneratedPluginRegistrant.registerWith(this);
}
}
where it was registering PluginRegistrant to that:
import io.flutter.embedding.android.FlutterActivity;
public class MainActivity extends FlutterActivity {
}

Since yesterday evening I've been unable to open my app in emulator. It worked fine till then.
Launching lib\main.dart on Android SDK built for x86 in debug mode...
lib\main.dart:1
√ Built build\app\outputs\flutter-apk\app-debug.apk.
It usually takes about 2 mins to open but it was just stuck there for like 15 mins. So I looked up for answers and the first one said to use gradlew clean and gradlew build. I did that and still was stuck but with another error.
Launching lib\main.dart on Android SDK built for x86 in debug mode...
lib\main.dart:1
Note: C:\flutter\.pub-cache\hosted\pub.dartlang.org\path_provider_android-2.0.12\android\src\main\java\io\flutter\plugins\pathprovider\PathProviderPlugin.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
√ Built build\app\outputs\flutter-apk\app-debug.apk.
Then I tried an answer from a similar question here that suggested to do flutter pub cache repair. Still no luck.
Then I tried another suggestion from an answer here to upgrade flutter. I hadn't upgraded flutter for a couple months since so I did that but still the issue persists.
I read from a comment to a question here that when they run the project using flutter run -v in terminal it opened up after about 20 mins. So I started it and because my laptop is like 6 years old running 6th gen i5 with 8gb ram I thought it might take a bit longer. So I left it there and now after about 2 hours my terminal is stuck at:
I hit the question character limit so I put the terminal's output in
an online notepad at: https://anotepad.com/notes/3jri4gpc
I just closed the emulator and the terminal added this to the above

From [+7331895 ms] executing: in the first line after closing the emulator I can see that this was running for about 122 minutes.
I don't understand what's wrong here. Why did the emulator stop working normally all of a sudden?
How to make it work so that I can continue with my app development? Please help.

When I run the objectbox_generator with flutter packages pub run build_runner watch the classes are being generated in the JSON, but shortly after that the Generation fails due to a null check issue. I checked my code and couldn't find any null check issues. Is there a way to show more detailed logs (e.g. where it is located) ?

From the code it looks like you have a #Backlink() to an unknown entity (one that is not stored in the DB)... try to check those backlinks (and comment them out to see if that works) and when you've found which one triggers this, consider opening an issue on objectbox-dart's GitHub with the minimal example.
P. S. as for the null check failure - yeah, needs a better error (one that tells you about the missing entity) - https://github.com/objectbox/objectbox-dart/commit/00aabe224eaa9bb88ab2bc18a5c31f00b4f3bdc0

However when i open my application in Android module in Android Studio then it runs fine but when i tried to run with Flutter i got that error.
Using Android Studio may prompt you to upgrade the project's settings (i.e. gradle version). A quick fix for this issue is by downgrading to the project's previous gradle version as previously mentioned in the comments. You can also try going through suggestions posted on this GitHub issue thread ahttps://github.com/flutter/flutter/issues/45681 and see if anything works for you.
