Update column type laravel migration

Laravel migration update table column type

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

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

Laravel migration change column type

public function up()
{
    Schema::table('sometable', function (Blueprint $table) {
        $table->text('text')->change();
    });
}

Laravel migration column types

# nullableTimestamps()
## alias of the timestamps method
	$table->nullableTimestamps(0);

# nullableMorphs()
## The method is similar to the morphs method 
## however, the columns that are created will be "nullable":
	$table->nullableMorphs('taggable');

# nullableUuidMorphs()
## The method is similar to the uuidMorphs method
## however, the columns that are created will be "nullable":
    $table->nullableUuidMorphs('taggable');

# point()
## creates a POINT equivalent column:
    $table->point('position');

# polygon()
## creates a POLYGON equivalent column:
    $table->polygon('position');

# rememberToken()
## creates a nullable, VARCHAR(100) equivalent column 
## that is intended to store the current "remember me" authentication token:
    $table->rememberToken();

# set()
## creates a SET equivalent column with the given list of valid values:
    $table->set('flavors', ['strawberry', 'vanilla']);

# smallIncrements()
## creates an auto-incrementing UNSIGNED SMALLINT 
## equivalent column as a primary key:
    $table->smallIncrements('id');

# smallInteger()
## creates a SMALLINT equivalent column:
    $table->smallInteger('votes');

# softDeletesTz()
## adds a nullable deleted_at TIMESTAMP (with timezone) equivalent column 
## with an optional precision (total digits). 
## This column is intended to store the deleted_at timestamp 
## needed for Eloquent's "soft delete" functionality:
    $table->softDeletesTz($column = 'deleted_at', $precision = 0);

# softDeletes()
## adds a nullable deleted_at TIMESTAMP 
## equivalent column with an optional precision (total digits). 
## This column is intended to store the deleted_at timestamp 
## needed for Eloquent's "soft delete" functionality:
    $table->softDeletes($column = 'deleted_at', $precision = 0);

# string()
## creates a VARCHAR equivalent column of the given length:
    $table->string('name', 100);

# text()
## creates a TEXT equivalent column:
    $table->text('description');

# timeTz()
## creates a TIME (with timezone) 
## equivalent column with an optional precision (total digits):
    $table->timeTz('sunrise', $precision = 0);

# time()
## creates a TIME equivalent column with an optional precision (total digits):
    $table->time('sunrise', $precision = 0);

# timestampTz()
## creates a TIMESTAMP (with timezone) 
## equivalent column with an optional precision (total digits):
    $table->timestampTz('added_at', $precision = 0);

# timestamp()
## creates a TIMESTAMP equivalent column 
## with an optional precision (total digits):
    $table->timestamp('added_at', $precision = 0);

# timestampsTz()
## creates created_at and updated_at TIMESTAMP 
## (with timezone) equivalent columns with an optional precision (total digits):
    $table->timestampsTz($precision = 0);

# timestamps()
## creates created_at and updated_at TIMESTAMP 
## equivalent columns with an optional precision (total digits):
    $table->timestamps($precision = 0);

# tinyIncrements()
## creates an auto-incrementing UNSIGNED TINYINT 
## equivalent column as a primary key:
    $table->tinyIncrements('id');

# tinyInteger()
## creates a TINYINT equivalent column:
    $table->tinyInteger('votes');

# tinyText()
## creates a TINYTEXT equivalent column:
    $table->tinyText('notes');

# unsignedBigInteger()
## creates an UNSIGNED BIGINT equivalent column:
    $table->unsignedBigInteger('votes');

# unsignedDecimal()
## creates an UNSIGNED DECIMAL equivalent column with 
## an optional precision (total digits) 
## and scale (decimal digits):
    $table->unsignedDecimal('amount', $precision = 8, $scale = 2);

# unsignedInteger()
## creates an UNSIGNED INTEGER equivalent column:
    $table->unsignedInteger('votes');

# unsignedMediumInteger()
## creates an UNSIGNED MEDIUMINT equivalent column:
    $table->unsignedMediumInteger('votes');

# unsignedSmallInteger()
## creates an UNSIGNED SMALLINT equivalent column:
    $table->unsignedSmallInteger('votes');

# unsignedTinyInteger()
## creates an UNSIGNED TINYINT equivalent column:
    $table->unsignedTinyInteger('votes');

# uuidMorphs()
## The uuidMorphs method is a convenience method that adds a 
## {column}_id CHAR(36) equivalent column and a {column}_type 
## VARCHAR equivalent column.
## This method is intended to be used when defining the columns necessary 
## for a polymorphic Eloquent relationship that use UUID identifiers. 
## In the following example, `taggable_id` and `taggable_type` columns would be created:
    $table->uuidMorphs('taggable');

# uuid()
## creates a UUID equivalent column:
    $table->uuid('id');

# year()
## creates a YEAR equivalent column:
    $table->year('birth_year');
