laravel migration set default value

$table->increments('id');
            $table->string('name');
            $table->string('url');
            $table->string('country');
            $table->tinyInteger('status')->default('1');
            $table->timestamps();

Schema::table('users', function ($table) {
    $table->integer('active')->default(0)->change();
});

$table->integer('parent_item_category_id')->nullable();

You can use change() method:

Schema::table('users', function ($table) {
    $table->integer('active')->default(0)->change();
});
