iOS and Android build failed and null-safety?

[ivangalkindeveloper]

Hello,

1. When launching the application on an iOS device, the following error occurs:

Xcode's output:
↳
    /Users/ivangalkin/Development/My projects/BReminder/ios/Runner/AppDelegate.swift:3:8: error: compiling for iOS 9.0, but module 'flutter_ok_sdk' has a minimum deployment target of iOS 10.0: /Users/ivangalkin/Development/My projects/BReminder/build/ios/Debug-iphonesimulator/flutter_ok_sdk/flutter_ok_sdk.framework/Modules/flutter_ok_sdk.swiftmodule/x86_64-apple-ios-simulator.swiftmodule
    import flutter_ok_sdk
           ^

Before starting , of course, I reinstall the pods

2. When launching the application on Android device, the following error occurs:

FAILURE: Build failed with an exception.

* What went wrong:
The Android Gradle plugin supports only Kotlin Gradle plugin version 1.3.40 and higher.
The following dependencies do not satisfy the required version:
project ': flutter_ok_sdk' -> org.jetbrains.kotlin: kotlin-gradle-plugin: 1.3.0

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

Build.gradle:

buildscript {
    ext.kotlin_version = '1.5.10'
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.0.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.10'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

3. Is it possible to update the SDK to null-safety?
