isar 4.0.0-dev.13

Extremely fast, easy to use, and fully async NoSQL database for Flutter.

4.0.0-dev.13

⚠️ ISAR V4 IS NOT READY FOR PRODUCTION USE ⚠️

This version does not support database migration yet and cannot open Isar v3 databases. The stable version will be released in a few weeks and will support migration from v3.

Breaking

Changed transactions API:

old	new
writeTxn()	writeAsync()
writeTxnSync()	write()
txn()	readAsync()
txnSync()	read()

• All operations are now synchronous by default and there are Async methods for asynchronous operations.
• Ids now need to be called id or annotated with @id
• Ids can no longer be nullable. There is a new collection.autoIncrement() function to automatically generate ids.
• Enums no longer need to be annotated with @enumerated instead there is a new @enumValue annotation to specify the value property of an enum
• Where clauses have been removed in favor of automatic index handling
• Isar links have been removed in favor of embedded objects
• Indexes have been simplified
• The Android minimum SDK version is now 23

Enhancements

• Encrypted databases
• String ids
• Fetching multiple properties simultaneously
• Partial and Bulk updates using collection.update() and query.updateAll()
• SQLite storage engine support
