I know this is a common theme on Stack Overflow–about people breaking their Flutter apps–but I can’t figure out how I broke mine. It worked this morning. I created a new flutter project, which was failing to compile. I tried switching channels and upgrading. But when I came back to my other existing app, it won’t compile now.
I have another app that works, so I tried putting all the dependencies and such to match. Same channel. Same SDK version, etc. Still broken.
HERE’S MY PUBSPEC.YAML:

HERE’S MY APP-LEVEL BUILD.GRADLE (which I’ve bumped the compileSdkVersion to 34 because the compiler recommended it):
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.")
}
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '1'
}
def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
flutterVersionName = '1.0'
}
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'

android {

signingConfig signingConfigs.debug
}
}
