Question

I'm new to flutter and am trying to run a new project on VS code.
installed the latest flutter at 19/1/2022. flutter --version gives me 2.8.1.
jdk is 17.0.1
this is what i get ...

i have tried changing the build.gradle in android/app/src
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.example.flutter_application_2"
minSdkVersion flutter.minSdkVersion
targetSdkVersion flutter.targetSdkVersion
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}
to
defaultConfig {
applicationId "com.example.gfgpagination"
minSdkVersion 19
targetSdkVersion 30
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
and it was not helpfull.
have tried searching these errors but i could not use them to this day.
my build.gradle in android folder
buildscript {
ext.kotlin_version = '1.3.50'
repositories {
google()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:4.1.0'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
allprojects {
repositories {
google()
mavenCentral()
}
}
rootProject.buildDir = '../build'
subprojects {
project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
project.evaluationDependsOn(':app')
}
task clean(type: Delete) {
delete rootProject.buildDir
}
and my build.gradle in android/app folder
def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
localPropertiesFile.withReader('UTF-8') { reader ->
localProperties.load(reader)
}
}
def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

if (flutterVersionCode == null) {
flutterVersionCode = '1'

Answer 1

soooo, I am going to answer my own question.
it seems i was using the latest java SDK version.
As mentioned in the install web page, i must have downloaded java SDK8 .
that's probably everything i did to fix it.

Answer 2

Try this for last error 'Unable to make field private final java.lang.String java.io.File.path' : https://exerror.com/accessible-module-java-base-does-not-opens-java-io-to-unnamed-module/

In your Manifest.xml add below line if it is not present:
