sqlite3_flutter_libs
This package intentionally contains no Dart code. Flutter apps depending on this package will
contain native sqlite3
libraries on Android, iOS, macOS, Linux and Windows.
For more details on how to actually use this package in a Flutter app, see sqlite3.
The sqlite3 version compiled with this package uses the
recommended compile-time options.
Additionally, it ships the fts5
module by default (the json1
module is part
of the default build in recent sqlite3 versions).
No other modules are included in these builds.
Notes on Android
Included platforms
Note that, on Android, this library will bundle sqlite3 for all of the following platforms:
arm64-v8a
armeabi-v7a
x86
x86_64
If you don't intend to release to 32-bit x86
devices, you'll need to apply a
filter in your build.gradle
:
android {
defaultConfig {
ndk {
abiFilters 'armeabi-v7a', 'arm64-v8a', 'x86_64'
}
}
}
Problems on Android 6
There appears to be a problem when loading native libraries on Android 6 (see this issue).
If you're seeing those crashes, you could try setting android.bundle.enableUncompressedNativeLibs=false
in your gradle.properties
file. Be aware that this increases the size of your application when installed.
Alternatively, you can use the applyWorkaroundToOpenSqlite3OnOldAndroidVersions
method from this library.
It will try to open sqlite3
in Java, which seems to work more reliably. After sqlite3 has been loaded from Java,
we can open it in Dart too.
The method should be called before using sqlite3
(either directly or indirectly through say a NativeDatabase
from package:drift
).
As applyWorkaroundToOpenSqlite3OnOldAndroidVersions
uses platform channels, there may be issues when using it on a background isolate.
We recommend awaiting it in the main isolate, before spawning a background isolate that might use the database.
Providing a temporary path
If you have complex queries failing with a SQLITE_IOERR_GETTEMPPATH 6410
error, you could try to explicitly set the
temporary path used by sqlite3. This comment contains a snippet
to do just that.
