Flutter项目fstore依赖版本冲突问题求助

冲突场景 #

场景1：初始版本冲突 #

项目指定intl: 0.17.0，但flutter_localizations（来自SDK）依赖intl 0.18.0，导致版本解析失败，报错如下：

Resolving dependencies...
Because fstore depends on flutter_localizations from sdk which depends on intl 0.18.0, intl 0.18.0 is required.
So, because fstore depends on intl 0.17.0, version solving failed.
Process finished with exit code 1

场景2：修改intl版本后的冲突 #

将intl版本改为0.18.0后，依赖的git版本charts_flutter要求intl >=0.15.2 <0.18.0，再次导致版本解析失败，报错如下：

Resolving dependencies...
Because every version of charts_flutter from git depends on intl >=0.15.2 <0.18.0 and fstore depends on intl 0.18.0, charts_flutter from git is forbidden.
So, because fstore depends on charts_flutter from git, version solving failed.
Process finished with exit code 1

可行解决方案 #

方案1：修改charts_flutter的依赖约束（推荐） #

1. Fork目标仓库到自己的账号下
2. 进入fork后的仓库，修改charts_flutter/pubspec.yaml中的intl依赖为：

   intl: ^0.15.2
   

   或更宽松的范围>=0.15.2 <0.19.0，确保兼容intl 0.18.0
3. 在项目的pubspec.yaml中，将charts_flutter的依赖指向自己的fork仓库：

   charts_flutter:
     git:
       url: https://github.com/你的账号名/charts.git
       path: charts_flutter
   

4. 执行flutter pub get完成依赖安装

方案2：使用dependency_overrides强制统一版本 #

在项目pubspec.yaml的末尾添加以下配置，强制所有依赖使用intl 0.18.0：

dependency_overrides:
  intl: 0.18.0

执行flutter pub get后，需全面测试charts_flutter相关功能，确保无兼容性问题。

方案3：降级Flutter SDK版本 #

降级到flutter_localizations依赖intl 0.17.0的Flutter版本（如3.3.x系列）：

flutter downgrade 3.3.10

此方法会限制SDK版本，不利于后续项目升级，仅作为临时解决方案。
