  ║ The Flutter tool uses Google Analytics to anonymously report feature usage ║
  ║ statistics and basic crash reports. This data is used to help improve      ║
  ║ Flutter tools over time.                                                   ║

  ║ Flutter tool analytics are not sent on the very first run. To disable      ║
  ║ reporting, type 'flutter config --no-analytics'. To display the current    ║
  ║ setting, type 'flutter config'. If you opt out of analytics, an opt-out    ║
  ║ event will be sent, and then no further information will be sent by the    ║
  ║ Flutter tool.                                                              ║

Resolving dependencies...


Because source_gen >=1.0.0 depends on dart_style ^2.0.0 and dart_style ^2.3.7 depends on analyzer ^6.5.0, source_gen >=1.0.0 requires analyzer ^6.5.0 or dart_style >=2.0.0 <2.3.7.
And because json_dynamic_widget_codegen >=1.0.6+1 depends on analyzer >=6.2.0 <6.5.0, if json_dynamic_widget_codegen >=1.0.6+1 and source_gen >=1.0.0 then dart_style >=2.0.0 <2.3.7.
And because json_dynamic_widget_codegen >=1.0.4+4 depends on source_gen ^1.5.0 and build_runner >=2.4.14 depends on dart_style >=2.3.7 <4.0.0, json_dynamic_widget_codegen >=1.0.6+1 is incompatible with build_runner >=2.4.14.
So, because json_dynamic_widget_plugin_svg depends on both build_runner ^2.4.14 and json_dynamic_widget_codegen ^2.0.0, version solving failed.


You can try the following suggestion to make the pubspec resolve:
* Consider downgrading your constraint on build_runner: flutter pub add dev:build_runner:^2.4.13
