Sources under `packages/flutter_tools/` aren't accessible to the average Flutter user by navigating through sources from their projects, so it doesn't need to be as explicitly verbose with types for readability purposes. The `always_specify_types` lint results in extremely verbose code within the tool which adds little value. This change disables `always_specify_types` in favor of a new set of lints that aim to reduce verbosity by removing obvious types while also maintaining readability in cases where variable types otherwise wouldn't be obvious: - `omit_obvious_local_variable_types` - `omit_obvious_property_types` - `specify_nonobvious_local_variable_types` - `specify_nonobvious_property_types`
