ext_theme can not use with dart_json_mapper.

Hi, I am using your library and dart_json_mapper. Both use Reflection to generate the file. Your library requires a very new version of Reflection, so the two cannot be used together. Can you reduce the version Reflection is using in your library?

And because dart_json_mapper >=1.2.0 <1.2.7 depends on reflectable ^2.2.0 and dart_json_mapper >=1.1.12 <1.2.0 depends on reflectable ^2.1.0, dart_json_mapper <0.1.1-∞ or >=0.1.3 <1.1.0-∞ or >=1.1.12 <1.5.16-∞ requires build ^0.12.0 or reflectable ^2.1.0.
And because dart_json_mapper >=1.1.11 <1.1.12 depends on reflectable ^2.0.12 and dart_json_mapper >=1.1.2 <1.1.11 depends on reflectable ^2.0.10+1, dart_json_mapper <0.1.1-∞ or >=0.1.3 <1.1.0-∞ or >=1.1.2 <1.5.16-∞ requires build ^0.12.0 or reflectable ^2.0.10+1.
And because dart_json_mapper >=1.1.0 <1.1.2 depends on reflectable ^2.0.8 and dart_json_mapper >=0.1.1 <0.1.3 depends on reflectable ^2.0.0, dart_json_mapper <1.5.16 requires build ^0.12.0 or reflectable ^2.0.0.

And because dart_json_mapper >=2.1.13 <2.1.17 depends on analyzer ^2.5.0 and dart_json_mapper >=2.1.7 <2.1.13 depends on analyzer ^2.2.0, dart_json_mapper <1.5.16-∞ or >=2.1.7 requires build ^0.12.0 or reflectable ^2.0.2 or analyzer ^2.2.0.
And because dart_json_mapper >=2.1.4 <2.1.7 depends on analyzer ^2.0.0 and dart_json_mapper >=2.1.3 <2.1.4 depends on analyzer ^1.7.0, dart_json_mapper <1.5.16-∞ or >=2.1.3 requires build ^0.12.0 or reflectable ^2.0.2 or analyzer ^1.7.0 or ^2.0.0.
And because dart_json_mapper >=2.1.0 <2.1.3 depends on analyzer ^1.5.0 and dart_json_mapper >=2.0.1 <2.1.0 depends on analyzer ^1.1.0, dart_json_mapper <1.5.16-∞ or >=2.0.1 requires build ^0.12.0 or reflectable ^2.0.2 or analyzer >=1.1.0 <2.0.0 or ^2.0.0.

And because dart_json_mapper >=1.5.16 <1.6.0 depends on reflectable ^2.2.5 and every version of ext_theme_generator depends on analyzer ^3.1.0, if dart_json_mapper any and ext_theme_generator any then build ^0.12.0 or reflectable ^2.0.2.
Because reflectable >=2.0.2 <3.0.0-nullsafety.0 depends on logging ^0.11.0 and build >=2.0.0 depends on logging ^1.0.0, reflectable >=2.0.2 <3.0.0-nullsafety.0 is incompatible with build >=2.0.0.
Thus, one of build >=2.0.0 or dart_json_mapper any or ext_theme_generator any must be false.
And because every version of ext_theme_generator depends on build ^2.2.1, dart_json_mapper is incompatible with ext_theme_generator.
So, because langlearning depends on both dart_json_mapper any and ext_theme_generator any, version solving failed.

Hi @o7planning,

Thank you for filing this issue! I wasn't aware that people were already using this package!

I will try to find some time to look into this!
