not able to install in laravel 6 and php 8

[dilipmp]

Problem 1 - Root composer.json requires beyondcode/laravel-dump-server ^1.7 -> satisfiable by beyondcode/laravel-dump-server[1.7.0]. - beyondcode/laravel-dump-server 1.7.0 requires symfony/var-dumper ^5.0 -> found symfony/var-dumper[v5.0.0-BETA1, ..., 5.4.x-dev] but the package is fixed to v4.4.34 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
