flutter picture sizer code example
Example 1: how to get image file size in flutter
final bytes = image.readAsBytesSync().lengthInBytes;
final kb = bytes / 1024;
final mb = kb / 1024;
Example 2: resize image flutter
assets.forEach((asset) {
Future<ByteData> byteData = asset.getByteData();
byteData.then((d) async {
List<int> imageData = d.buffer.asUint8List();
String b64 =base64Encode(imageData);
print(b64);
ui.instantiateImageCodec(imageData,targetHeight: 800, targetWidth: 600)
.then((codec) {
codec.getNextFrame().then((frameInfo) async {
ui.Image i = frameInfo.image;
ByteData bytes = await i.toByteData();
List<int> resizedImageData = bytes.buffer.asUint8List();
String rb64 = base64Encode(resizedImageData);
print(rb64);
});
});
});
});
