GitLab CI构建Flutter App Bundle时遭遇段错误

我的CI配置

variables:
  PLAY_STORE_JSON: $PLAY_STORE_JSON
  KEY_PROPERTIES: $KEY_PROPERTIES
  UPLOAD_KEYSTORE: $UPLOAD_KEYSTORE

build:bundle:
  stage: build
  image: cirrusci/flutter:3.3.5
  tags:
    - docker-app-dev
  before_script:
    - cd android
    - echo $KEY_PROPERTIES > key.properties
    - echo $UPLOAD_KEYSTORE > app/upload-keystore.jks
  script:
    - flutter clean
    - flutter build appbundle
  after_script:
    - rm -f ./android/app/upload-keystore.jks ./android/key.properties

报错信息

../../runtime/bin/eventhandler_linux.cc: 416: error: Failed to start event handler 

thread 1
===== CRASH =====

解决思路

修复密钥文件写入方式：echo无法正确处理二进制的keystore文件，会导致文件损坏进而引发异常。先把本地的upload-keystore.jks用base64编码（执行base64 upload-keystore.jks），将编码后的内容更新到GitLab的UPLOAD_KEYSTORE变量中，然后修改CI配置中的写入命令：
```
before_script:
  - echo "$KEY_PROPERTIES" > android/key.properties
  - echo "$UPLOAD_KEYSTORE" | base64 -d > android/app/upload-keystore.jks
```
同时去掉cd android的步骤，保持在项目根目录操作，避免后续flutter命令路径错误。
更换Flutter镜像：cirrusci/flutter:3.3.5可能存在环境兼容性问题，换成官方Flutter镜像试试，比如flutter:3.3.5或者更新到更稳定的版本（如3.7.12）：
```
image: flutter:3.7.12
```
检查Runner资源：段错误常和内存不足有关，确认GitLab Runner分配的内存足够，必要时调整Runner的资源限制参数。
