SDK is Incompatible

[yosus]

Hi,

I tried using "gpx: ^1.1.1" and pub-get returns this error :

Because every version of flutter from sdk depends on meta 1.1.8 and xml >=4.3.0 depends on meta ^1.2.0, flutter from sdk is incompatible with xml >=4.3.0.
And because gpx >=1.0.1+2 depends on xml ^4.3.0, flutter from sdk is incompatible with gpx >=1.0.1+2.
So, because flutter_app depends on both flutter any from sdk and gpx ^1.1.1, version solving failed.
pub get failed (1; So, because flutter_app depends on both flutter any from sdk and gpx ^1.1.1, version solving failed.)

flutter doctor -v
