Usage Examples

Simple File Upload

// returns url pointing to S3 file

SimpleS3 _simpleS3 = SimpleS3();
String result = await _simpleS3.uploadFile(
				file, <--------------- Selected File
				bucketName, <--------- Your Bucket Name
				poolID, <------------- Your POOL ID
				AWSRegions.apSouth1 <- S3 server region
				);

Delete

// returns bool

bool result = await SimpleS3.delete(
				filePath, <---------------- S3 File Path
				bucketName, <-------------- Your Bucket Name
				poolID, <------------------ Your POOL ID
				AWSRegions.apSouth1, <----- S3 server region
				);

// delete also supports sub-regions

File Upload with Percentage

// returns url pointing to S3 file

SimpleS3 _simpleS3 = SimpleS3();
//Upload function
String result = await _simpleS3.uploadFile(
				file, <--------------- Selected File
				bucketName, <--------- Your Bucket Name
				poolID, <------------- Your POOL ID
				AWSRegions.apSouth1 <- S3 server region
				);

//Widget
child: StreamBuilder<dynamic>(  
    stream: _simpleS3.getUploadPercentage,  
    builder: (context, snapshot) {  
      return new Text(  
        snapshot.data != null ? "Uploaded: ${snapshot.data}" : "Simple S3",  
    );  
  }),

Custom File Name

// returns url pointing to S3 file

SimpleS3 _simpleS3 = SimpleS3();
String result = await _simpleS3.uploadFile(
				file, <------------------------------ Selected File
				bucketName, <------------------------ Your Bucket Name
				poolID, <---------------------------- Your POOL ID
				AWSRegions.apSouth1, <--------------- S3 server region
				fileName: "Dennis_ritchie.jpeg", <--- Custom file name
				);

Custom S3 Path

// returns url pointing to S3 file

SimpleS3 _simpleS3 = SimpleS3();
String result = await _simpleS3.uploadFile(
				file, <-------------------------------- Selected File
				bucketName, <--------------------------- Your Bucket Name
				poolID, <------------------------------- Your POOL ID
				AWSRegions.apSouth1, <------------------ S3 server region
				s3FolderPath: "users/profile_pics", <--- Custom S3 path
				);

// final path will be  "bucketName/users/profile_pics"

Setting Access Control

// returns url pointing to S3 file

SimpleS3 _simpleS3 = SimpleS3();
String result = await _simpleS3.uploadFile(
				file, <------------------------------------- Selected File
				bucketName, <------------------------------- Your Bucket Name
				poolID, <----------------------------------- Your POOL ID
				AWSRegions.apSouth1, <---------------------- S3 server region
				accessControl: S3AccessControl.private, <--- Setting access of uploaded file **private**
				);

// S3AccessControl have more types of AccessControl ex. .publicRead, .publicReadWrite etc...

Using Timestamp

// returns url pointing to S3 file

SimpleS3 _simpleS3 = SimpleS3();
String result = await _simpleS3.uploadFile(
				file, <------------------------------------- Selected File
				bucketName, <------------------------------- Your Bucket Name
				poolID, <----------------------------------- Your POOL ID
				AWSRegions.apSouth1, <---------------------- S3 server region
				useTimeStamp: true, <----------------------- Enable Timestamp
				);

// default location of timestamp is prefix
// if original file name = "Dennis_ritchie.jpeg"
// then the result will be = "1591705658_Dennis_ritchie.jpeg"


// Change Timestamp Location



SimpleS3 _simpleS3 = SimpleS3();
String result = await _simpleS3.uploadFile(
				file, <--------------------------------------- Selected File
				bucketName, <--------------------------------- Your Bucket Name
				poolID, <------------------------------------- Your POOL ID
				AWSRegions.apSouth1, <------------------------ S3 server region
				useTimeStamp: true, <------------------------- Enable Timestamp
				timeStampLocation: TimestampLocation.suffix,<- Changes timestamp location to suffix
				);
// if original file name = "Dennis_ritchie.jpeg"
// then the result will be = "Dennis_ritchie_1591705658.jpeg"

Using Sub-Region

// returns url pointing to S3 file

SimpleS3 _simpleS3 = SimpleS3();
String result = await _simpleS3.uploadFile(
				file, <------------------------------------- Selected File
				bucketName, <------------------------------- Your Bucket Name
				poolID, <----------------------------------- Your POOL ID
				AWSRegions.apSouth1, <---------------------- S3 server region
				subRegion: AWSRegions.apNorthEast1 <-------- Sub region
				);

Debug mode

// for security reasons plugin uses less logs, to enable full logs -

SimpleS3 _simpleS3 = SimpleS3();
String result = await _simpleS3.uploadFile(
				file, <--------------- Selected File
				bucketName, <--------- Your Bucket Name
				poolID, <------------- Your POOL ID
				AWSRegions.apSouth1 <- S3 server region
				debugLog: true, <----- Enable full logs
				);

Android Proguard settings for release mode

// add these lines in your app/build.gradle

		minifyEnabled true  
		useProguard true  
		proguardFiles getDefaultProguardFile('proguard-android.txt'),  
		        'proguard-aws-2.1.5.pro'

//EXAMPLE
		buildTypes {  
		  release {  
		  signingConfig signingConfigs.release  
		  minifyEnabled true  
		  useProguard true  
		  proguardFiles getDefaultProguardFile('proguard-android.txt'),  
		                'proguard-aws-2.1.5.pro'  
		  }  
		}

Now copy contents of this file proguard-aws-2.1.5.pro Create a new file with name "proguard-aws-2.1.5.pro" at the same location as app/build.gradle and paste the copied contents into this file.
