How to Update a row in Flutter with SQFlite - flutter

Question

I try to update a row, but nothing happens, I don't know what I have missed.
Could some please check what I have done wrong ?
This is my helper class.
class DBHelper {
static Future<sql.Database> database() async {
final dbPath = await sql.getDatabasesPath();
//einmal die Datenbank erstellen in einer Variablen
return sql.openDatabase(path.join(dbPath, 'wanderwege.db'),
onCreate: (db, version) {
return db.execute(
'CREATE TABLE user_places(id TEXT PRIMARY KEY, title TEXT, image TEXT, createTime TEXT, place TEXT, description TEXT)');
// 'CREATE TABLE user_places(id TEXT PRIMARY KEY, title TEXT, image TEXT, loc_lat REAL, loc_lng REAL, address TEXT)');
}, version: 1);
}
static Future<void> insert(String table, Map<String, Object> data) async {
final db = await DBHelper.database();
db.insert(table, data, conflictAlgorithm: sql.ConflictAlgorithm.replace);
}
//Delete data from table
static Future<void> delete(String id) async {
final db = await DBHelper.database();
var res = await db.delete('user_places', where: "id = ?", whereArgs: [id]);
return res;
}
//Update Data
static Future<void> updateData(String title) async {
final db = await DBHelper.database();
int res =
await db.rawUpdate('UPDATE user_places SET title = ? WHERE id = ?');
return res;
}
}
And on my Edit_Screen I used this,
first I just wanted to try to update the title, with the new value from _titleController.text
//Update für die jeweiligen einträge zu Kontrollieren
checkupdate() {
if (_titleController.text.isEmpty) {
var errorMessage = 'Bitte gib einen Titel ein';
return _showErrorDialog(errorMessage);
}
DBHelper.updateData(_titleController.text);
print(DBHelper.updateData(_titleController.text));
Navigator.of(context).pop();
}
But nothing happen, I dont now where exactly I have done the misstake.
Thanks for the help :)

I assume you miss update arguments in rawUpdate query.
//Update Data
static Future<void> updateData(String title, String id) async {
final db = await DBHelper.database();
int res =
await db.rawUpdate('UPDATE user_places SET title = ? WHERE id = ?', [title, id]);
return res;
}
Refer rawUpdate example here: https://pub.dev/packages/sqflite
