flutter pub add fails.

[Tejas-MD]

Terminal Command: flutter pub add height_slider
Terminal output :
Because height_slider >=1.4.0-nullsafety depends on flutter_svg ^0.21.0-nullsafety.0 and height_slider <1.2.0 depends on flutter_svg ^0.15.0, height_slider <1.2.0-∞ or >=1.4.0-nullsafety requires flutter_svg ^0.15.0 or ^0.21.0-nullsafety.0. And because height_slider >=1.2.0 <1.3.0 depends on flutter_svg ^0.17.4, height_slider <1.3.0-∞ or >=1.4.0-nullsafety requires flutter_svg ^0.15.0 or ^0.17.4 or ^0.21.0-nullsafety.0. And because height_slider >=1.3.0 <1.3.2 depends on flutter_svg ^0.19.1 and height_slider >=1.3.2 <1.4.0-nullsafety depends on flutter_svg ^0.19.3, every version of height_slider requires flutter_svg ^0.15.0 or ^0.17.4 or >=0.19.1 <0.20.0 or ^0.21.0-nullsafety.0. So, because demo_app depends on both flutter_svg ^1.1.5 and height_slider any, version solving failed.
