laravel migration update table column type

1Schema::table('users', function ($table) {
2    $table->string('name', 50)->change();
3});
4We could also modify a column to be nullable:

6Schema::table('users', function ($table) {
7    $table->string('name', 50)->nullable()->change();
8});

4        $table->text('text')->change();
5    });
