Скачать или смотреть #21 Validate Forms in flutter || Flutter Forms And Validation

Assalam U Alikum Friends In this video I have explain about validation Form Fields in Flutter. For validation I have also used Regular Expressions fore email and password validation.

For Email we have checked that @ and .com must be included. And for Password we have check that it must contain character and numbers both.

Regular Expressions Pattern:
Email RegExp Pattern: r"(^[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+$)"
Password RegExp Pattern: r'^(?=.*[0-9]+.*)(?=.*[a-zA-Z]+.*)[0-9a-zA-Z]{6,}$'
