You have to create a dummyDump.sql file in ‘assets/’ folder like this,
CREATE TABLE IF NOT EXISTS developer(id INTEGER PRIMARY KEY AUTOINCREMENT,name TEXT,skill TEXT,yearsOfExperience INTEGER);
INSERT INTO developer(name, skill, yearsOfExperience) VALUES ('Simon', 'Ionic', '4');
INSERT INTO developer(name, skill, yearsOfExperience) VALUES ('Jorge', 'Firebase', '2');
INSERT INTO developer(name, skill, yearsOfExperience) VALUES ('Max', 'Startup', '5');
Thanks.
