Failed migrations on Laravel 6.x

[qlixes]

first, I'm using Laravel 6.0, then tried to install laravel-firebird. I've found some error :

1. failed to migrations

       Schema::create('roles', function (Blueprint $table) {
           $table->useIdentity();
           $table->bigIncrements('id');
           $table->string('role_name')->unique();
           $table->boolean('all_branch')->default(false)->comment('access all branch');
           $table->boolean('is_active')->default(true);
           $table->timestamps();
       });

   because on Firebird Grammer, while had default value, it's doesn't need NOT NULL again.

Thank you a lot.

@qlixes Migrations aren't something that have been properly tested and I should probably add a warning in the readme. If you do require it, I'm open to PRs.
