.flutter-plugins-dependencies replaces .flutter-plugins.
Summary
#The flutter
tool will no longer output the .flutter-plugins
metadata file, and only output .flutter-plugins-dependencies
.
Tools and build scripts, such as Gradle configurations (for Android apps) that rely on the presence of .flutter-plugins
need to be updated.
Background
#In 2019, .flutter-plugins-dependencies
was added as a newer file format that replaces .flutter-plugins
.
So a file that looked something like this:
camera=/path/to/camera/plugin
shared_preferences=shared_preferences
Was replaced by something like this:
{
"dependencyGraph": {
"camera": {
"name": "camera",
"version": "0.10.0",
"dependencies": {
"flutter": "0.0.0"
}
},
"shared_preferences": {
"name": "shared_preferences",
"version": "2.0.15",
"dependencies": {
"flutter": "0.0.0"
}
}
},
"flutter": {
"frameworkRevision": "3a0f99d4f2",
"channel": "stable"
}
}
Generating both files is a source of technical debt that complicates new feature sets, such as not bundling dev_dependency
plugins in a release app.
Migration guide
#Most Flutter developers don't parse or use this file, but build configurations might, including the settings.gradle
file as generated by older invocations of flutter create --platforms android
. These legacy files might still reference .flutter-plugins
and must be updated to a newer build script.
For example:
include ':app'
def flutterProjectRoot = rootProject.projectDir.parentFile.toPath()
def plugins = new Properties()
// Note explicitly reading the legacy '.flutter-plugins' file.
def pluginsFile = new File(flutterProjectRoot.toFile(), '.flutter-plugins')
if (pluginsFile.exists()) {
pluginsFile.withReader('UTF-8') { reader -> plugins.load(reader) }
}
plugins.each { name, path ->
def pluginDirectory = flutterProjectRoot.resolve(path).resolve('android').toFile()
include ":$name"
project(":$name").projectDir = pluginDirectory
}
Might be upgraded to its settings.gradle.kts
equivalent:
pluginManagement {
val flutterSdkPath = run {
val properties = java.util.Properties()
file("local.properties").inputStream().use { properties.load(it) }
val flutterSdkPath = properties.getProperty("flutter.sdk")
require(flutterSdkPath != null) { "flutter.sdk not set in local.properties" }
flutterSdkPath
}
includeBuild("$flutterSdkPath/packages/flutter_tools/gradle")
repositories {
google()
mavenCentral()
gradlePluginPortal()
}
}
plugins {
// Note the use of the flutter-plugin-loader versus reading '.flutter-plugins'
id("dev.flutter.flutter-plugin-loader") version "1.0.0"
id("com.android.application") version "8.1.0" apply false
id("org.jetbrains.kotlin.android") version "1.8.22" apply false
}
include(":app")
For help switching to the newer plugin DSL, check out Deprecated imperative apply of Flutter's Gradle plugins.
To smoke test whether your build relies on a .flutter-plugins
file, you can use the feature flag explicit-package-dependencies
:
flutter config explicit-package-dependencies
Any build tools or scripts that might rely on the .flutter-plugins
file being output will now fail.
