Flutter--＞AAPT: error: resource android:attr/lStar not found.

更新Flutter 3.24.0之后, 打包出现AAPT: error: resource android:attr/lStar not found.问题, 这里出一个我的解决方案.

更新Flutter 3.24.0之后, Android编译sdk需要使用34, 否则就会出现很多问题…

由于很多库都不可能及时更新适配到Android sdk 34, 所以可以等pub get将子库拉取到本地之后, 在本地手动将compileSdkVersion或compileSdk修改为34,即可解决本文问题.

作为程序猿,那肯定不可能手动修改, 这种体力活是干不会的.

祭出本文干货dart脚本:

import 'dart:convert';
import 'dart:io';///
/// 新版本的flutter 3.24.0使用Android 34编译,
/// 所有子库不使用sdk 34编译的话, 就会在打包的时候报错.
/// ```
/// AAPT: error: resource android:attr/lStar not found.
/// ```
/// ```
/// android {
///     // Conditional for compatibility with AGP <4.2.
///     if (project.android.hasProperty("namespace")) {
///         namespace 'com.rmawatson.flutterisolate'
///     }
///
///     compileSdkVersion 34
///
///     defaultConfig {
///         minSdkVersion 16
///     }
/// }
/// ```
///
/// 此脚本用于在打包前, 修改子库的compileSdkVersion编译版本.
///
void main() async {final currentPath = Directory.current.path;print('脚本工作路径->$currentPath');//Android sdk compile sdk versionfinal compileSdk = 34;//获取所有依赖的子库final dependenciesFile = File("$currentPath/.flutter-plugins-dependencies");final androidDependencies =jsonDecode(dependenciesFile.readAsStringSync())?["plugins"]?["android"];if (androidDependencies is List) {int index = 0;for (final dependency in androidDependencies) {final name = dependency["name"];final path = dependency["path"];if (path != null) {print("正在修改[${index + 1}/${androidDependencies.length}]->$path -> compileSdk:$compileSdk");amendAndroidCompileSdkVersion(path, compileSdk);}index++;}}
}/// 核心修改方法
/// 修改子库flutter工程中android工程中`build.gradle`文件中的`compileSdkVersion`和`compileSdk`
/// [flutterPath] flutter工程路径
/// [compileSdk] 修改后的编译版本
void amendAndroidCompileSdkVersion(String flutterPath, int compileSdk) {final androidPath = "$flutterPath/android";final androidPathFile = File("$androidPath/build.gradle");if (androidPathFile.existsSync()) {final androidPathFileContent = androidPathFile.readAsStringSync();if (androidPathFileContent.contains("compileSdkVersion")) {//修改compileSdkVersionfinal newContent = androidPathFileContent.replaceAllMapped(RegExp(r"compileSdkVersion\s+(\d+)"), (match) {return "compileSdkVersion $compileSdk";});//修改compileSdkfinal newContent2 =newContent.replaceAllMapped(RegExp(r"compileSdk\s+(\d+)"), (match) {return "compileSdk $compileSdk";});//写入文件androidPathFile.writeAsStringSync(newContent2);print("修改成功->$androidPathFile", 250);}}
