[MohamedGawdat]

Description:

Summary

• Update connectivity_plus from ^6.1.3 to ^7.0.0 to resolve compatibility conflicts with Flutter ecosystem
• Update related core dependencies for compatibility: graphql, gql_exec, path_provider, hive_ce, plugin_platform_interface
• Adjust meta version to ^1.15.0 for flutter_test compatibility

Background

connectivity_plus ^6.x has been causing significant dependency conflicts with other popular Flutter packages, preventing projects from resolving dependencies successfully. Version 7.0.0 resolves these ecosystem compatibility issues.

Changes

• connectivity_plus: ^6.1.3 → ^7.0.0 (main update)
• graphql: ^5.2.0 → ^5.2.2
• gql_exec: ^1.0.0 → ^1.0.0+1
• path_provider: ^2.0.1 → ^2.1.5
• hive_ce: ^2.11.0 → ^2.13.2
• plugin_platform_interface: ^2.0.0 → ^2.1.8
• meta: adjusted to ^1.15.0 for flutter_test compatibility

Test plan

• All dependencies resolve successfully with flutter pub get
• No breaking changes to existing API
• Maintains compatibility with existing codebase
• Run existing test suite to ensure no regressions
• Verify connectivity functionality works as expected
