when i use
analyzer: ^8.0.0
build: ^4.0.0
source_gen: ^4.0.0

the build broken due the package: test that in flutter stable is pinned to 1.26.2 (currently not supports analyzer: ^8.0.0)

Note: matcher is pinned to version 0.12.17 by flutter_test from the flutter SDK.
See https://dart.dev/go/sdk-version-pinning for details.

Note: test_api is pinned to version 0.7.6 by flutter_test from the flutter SDK.
See https://dart.dev/go/sdk-version-pinning for details.

Because test >=1.25.9 <1.26.3 depends on analyzer >=6.0.0 <8.0.0 and test >=1.21.6 <1.24.4 depends on analyzer >=2.0.0 <6.0.0,
  test >=1.21.6 <1.24.4-∞ or >=1.25.9 <1.26.3-∞ requires analyzer >=2.0.0 <6.0.0 or >=6.0.0 <8.0.0.
And because test >=1.21.0 <1.21.6 depends on analyzer >=2.0.0 <5.0.0, test >=1.21.0 <1.24.4-∞ or >=1.25.9 <1.26.3-∞ requires
  analyzer >=2.0.0 <6.0.0 or >=6.0.0 <8.0.0.

(1) So, because test >=1.24.3 <1.25.13 depends on matcher >=0.12.16 <0.12.17 and test >=1.26.3 depends on test_api 0.7.7, test
>=1.21.0 requires analyzer >=2.0.0 <6.0.0 or >=6.0.0 <8.0.0 or matcher >=0.12.16 <0.12.17 or test_api 0.7.7.

Because test >=1.17.10 <1.20.0 depends on analyzer >=1.0.0 <3.0.0 and test >=1.16.6 <1.17.10 depends on analyzer ^1.0.0, test
  >=1.16.6 <1.20.0 requires analyzer >=1.0.0 <3.0.0.
And because test >=1.20.0 <1.21.2 depends on test_api 0.4.9, test >=1.16.6 <1.21.2 requires analyzer >=1.0.0 <3.0.0 or test_api
  0.4.9.
And because test >=1.21.0 requires analyzer >=2.0.0 <6.0.0 or >=6.0.0 <8.0.0 or matcher >=0.12.16 <0.12.17 or test_api 0.7.7
  (1), test >=1.16.6 requires analyzer >=1.0.0 <6.0.0 or >=6.0.0 <8.0.0 or matcher >=0.12.16 <0.12.17 or test_api 0.4.9 or 0.7.7.

(2) So, because every version of flutter_test from sdk depends on both matcher 0.12.17 and test_api 0.7.6, if flutter_test from sdk
and test >=1.16.6 then analyzer >=1.0.0 <6.0.0 or >=6.0.0 <8.0.0.

Because no versions of source_gen match >4.0.0 <4.0.1 and source_gen >=4.0.1 depends on analyzer ^8.1.1, source_gen >4.0.0
  requires analyzer ^8.1.1.
And because source_gen 4.0.0 depends on build ^3.0.0 and every version of go_router_builder from path depends on build ^4.0.0,
  if source_gen >=4.0.0 and go_router_builder from path then analyzer ^8.1.1.
And because if flutter_test from sdk and test >=1.16.6 then analyzer >=1.0.0 <6.0.0 or >=6.0.0 <8.0.0 (2), one of flutter_test
  from sdk or test >=1.16.6 or source_gen >=4.0.0 or go_router_builder from path must be false.
And because every version of go_router_builder from path depends on source_gen ^4.0.0 and go_router_builder_example depends on
  flutter_test from sdk, test >=1.16.6 is incompatible with go_router_builder from path.
So, because go_router_builder_example depends on both go_router_builder from path and test ^1.17.0, version solving failed.

so as a workaround to be able to use the new version of analyzer I ended using version range
Curiously, doing this allows the installation of analyzer ^8
Additionally I think this would an intermediate version in order to be not wait until next flutter version (beta branch contains meta: 1.26.3)
additionally i wish in a near future (next flutter release) migrate away Elements2 like mentioned here PR#9649

As a note the currents checks do a test with both ranges (see Linux analyze stable)

analyzer: ^8.0.0
build: ^4.0.0
source_gen: ^4.0.0

and for downgrade (see Linux analyze_downgraded stable)

analyzer: ^7.0.0
build: ^3.0.0
source_gen: ^3.0.0

can you add a todo to use pinned version once the new stable rolled in?

For downgrade, check we can opt out for this package when we ready to pin the version

I can follow up on this so we can get this in.
