This app is taken from an android course from their site. Once I re-download the same exact code the errors are not present. The code is the same but one has errors. [Errors are shown in the image][1] [1]: https://i.stack.imgur.com/zkk8e.png
Dao
```import androidx.room.Dao
import androidx.room.Delete
import androidx.room.Insert
import androidx.room.OnConflictStrategy
import androidx.room.Query
import androidx.room.Update
import kotlinx.coroutines.flow.Flow
/**
* Database access object to access the Inventory database
*/
@Dao
interface ItemDao {
@Query("SELECT * from item ORDER BY name ASC")
fun getItems(): Flow<List<Item>>
@Query("SELECT * from item WHERE id = :id")
fun getItem(id: Int): Flow<Item>
// Specify the conflict strategy as IGNORE, when the user tries to add an
// existing Item into the database Room ignores the conflict.
@Insert(onConflict = OnConflictStrategy.IGNORE)
suspend fun insert(item: Item)
@Update
suspend fun update(item: Item)
@Delete
suspend fun delete(item: Item)
}```
Entity
```import androidx.room.ColumnInfo
import androidx.room.Entity
import androidx.room.PrimaryKey
import java.text.NumberFormat
/**
* Entity data class represents a single row in the database.
*/
@Entity
data class Item(
@PrimaryKey(autoGenerate = true)
val id: Int = 0,
@ColumnInfo(name = "name")
val itemName: String,
@ColumnInfo(name = "price")
val itemPrice: Double,
@ColumnInfo(name = "quantity")
val quantityInStock: Int,
)```
Most android applications generate errors like these without even touching the code. Why is that?
