Flutter Pub Get Error when trying to run some old project

Evening All,
I am was trying to run some old project in github but when trying to run pub get having this kind of error
Running "flutter pub get" in budgex...
Because flutter_html >=2.0.0-nullsafety.1 depends on html >=0.15.0 <1.0.0 and every version of link_previewer depends on html ^0.14.0+2, flutter_html >=2.0.0-nullsafety.1 is incompatible with link_previewer.
So, because budgex depends on both link_previewer ^1.2.1 and flutter_html ^2.2.1, version solving failed.
pub get failed (1; So, because budgex depends on both link_previewer ^1.2.1 and flutter_html ^2.2.1, version solving failed.)
exit code 1
i am already change some dependencies into latest version without local package folder and files from plugin here is the pubspec.yaml

Anyone can help this problem? appreciated it for helping

One of the way to solve above problem is, rather than specifying version code beside of any package you can just do below thing
flutter_html:
link_previewer:
...

you will need to update your dependencies so that they are compatible with each other. You can do this by modifying the version constraints in your pubspec.yaml file. For example, if you change the version constraint for html in link_previewer to be compatible with the constraint in flutter_html, you should be able to run flutter pub get
It is also possible that a newer version of link_previewer or flutter_html may have been released that resolves this conflict, so you may want to check for updates to these packages. However, be sure to carefully review the changelog for any updates to make sure that they won't break your project.
This error indicates that there is a conflict between the versions of link_previewer and flutter_html

flutter AAPT: error: resource android:attr/lStar not found

I'm trying to build the apk of my project but I got:
* What went wrong:
Execution failed for task ':audioplayers:verifyReleaseResources'.
> A failure occurred while executing com.android.build.gradle.tasks.VerifyLibraryResourcesTask$Action
> Android resource linking failed
ERROR:C:\Users\pc\.gradle\caches\transforms-3\1c118aff0ddf4faaf93ec03867fed550\transformed\core-1.9.0-rc01\res\values\values.xml:104:5-113:25: AAPT: error: resource android:attr/lStar not found.
I don't know what this means, nor how to solve it, I saw online that I should have this line
implementation "androidx.core:core-ktx:1.6.0"
in mine app/build.grande but I tried and nothing changes.
Plugins I'm currently using:
cupertino_icons: ^1.0.5
path_provider: ^2.0.11
encrypt: ^5.0.1
flutter_speed_dial: ^6.0.0
telephony: ^0.2.0
audioplayers: any
flutter_audio_recorder2: ^0.0.2

flutter_launcher_icons: ^0.9.0
camera: ^0.10.0+1
image_picker: any
imgur: any
permission_handler: ^10.0.0
flutter_sms: ^2.3.3
audio_session: ^0.1.10
flutter_sound: ^9.2.13
flutter_sound_platform_interface: ^9.2.13
lottie: ^1.4.1

environment: ^0.0.2
argon_buttons_flutter: ^1.1.0
flutter_native_splash: ^2.2.7
background_sms: ^0.0.4
animations: ^2.0.3

Override the http package to the latest one by including dependency_overrides in the pubspec.yaml. It's going to be like the following:
dependency_overrides:
http:
version: ">=0.13.5"
Also, set audioplayers version to ^1.0.1.
dependencies:
audioplayers: ^1.0.1

But in my android folder shows unused dependencies . Anyone can explain this and how to remove this from project ?
Ex:package_info_plus

I am not sure if I am giving the correct answer but, this may be because each flutter package/plugin may depend on others. If you see the device_info_plus on pub.dev you will see its dependencies. See the below image.

Undefined symbol OBJC Class in Flutter

I'm trying to build my flutter project but I'm getting this error so I'm just wondering how can I fix this. This happens after adding the Cookie Manager plugin. I can run the app on an emulator and physical device without any problem but it gives me this error when I try to build it.
